Uplander electric brake control installation

Does anyone know how to install an electric brake controller on a 2007 Uplander?
I need to connect the red wire of the controller to the cold side of the brake pedal. There are 3 wires on the uplander brake pedal, 1 with 10V constant, 1 with no power (Assuming ground) and 1 with 2.3V constant, goes to 5.10V when brake pedal is pushed in.
I would assume that I need to connect to the last wire but affraid because of the constant voltage at the switch.
Any help would be appreciated

.

Here's the info I found so far...

----------

"Roadmaster Inc makes a mounting bracket and wiring kit #751426. The kit is made for making an Uplander towable behind a motorhome, but should be ok to wire into a brake controller. The reason this switch is needed is because the factory switch on the brake pedal isn't an On/Off switch. It's a variable resistance switch going to the BCM (Body Control Module). The BCM outputs to the rear brake light through a white wire on connector 2 pin 30. The problem with this wire is that when no brake is applied there is still 2 volts present. I hope this helps."

Road Master Inc -> how to install OFF/ON switch on vehicle's brake pedal.

http://www.roadmasterinc.com/pdf/751426.pdf

Note: 12Volt 12 guage wire goes from Battery "+" post to 10A inline fuse, to 751426 (foot brake peddle switch), to newly installed Brake Controller's Red wire. When the van's brake peddle is pressed, the "extra" brake pedal off/on switch is "closed", and the Brake Controller unit is then 12V powered. Take foot off brake pedal, brake pedal switch "opens", and no more 12V power to Brake Controller. And, one doesn't need to TAP into the vehicle's factory 12V wiring (and its factory brake switch - that feeds into vehicle's BCM unit).

If wondering.... If my new '09 Montana EWB has a factory "variable resistance " brake pedel switch as well, I'm going to order/install Road Master Brake Switch (re: mounting bracket and wiring kit #751426) for my future Brake Controller as well.

Might have found a much better (simpler and lower cost) answer for you.

Thanks.
I was able to pinpoint the exact location using alldata.
I will try it this weekend.

After getting your brake controller properly connected, do test with 4-way emergency flashers activated as well. Depending on how the system is wired in, the vehicle's 4-way flasher may make the brake controller "pulse" as well. Thus, why some folks also install an anti-pulse device. And, why some folks install seperate Brake Pedal off/on switch as well. re: RoadMaster brake switch method instead of connecting to vehicle's BCM unit.

When you get your van's new brake controller installed (and fully tested), please advise how you did it. In late April, I plan to install an electric brake controllre in my new '09 Montana van as well. Would like to copy your install method as well. Thus, please share what works for you (and your '07 Uplander van).

thanks.

While doing some more "surfing", I found related Electric Brake Controller install on a Winstar van - that has the same "low voltage" current on its factory brake peddle switch as well.

For more details, surf entire thread of:
http://www.irv2.com/forums/showthread.php?t=21923
http://rides.webshots.com/photo/2882672600056340866fmdCMN

To fix their situation, they applied:
A - Found wires tucked above the brake pedal. Assume brake signal wires out of BCM.
B - Used a Brake Controller that ignored the lower 3 volts (of the brake switch wire).

For the '07 / '09 Uplander/Montana vans, I wonder if Fix A is under van's dash as well? If not, I wonder if our purchased brake controller ignores the +3 volts (used for light bulb management current)??? Sounds like emails to our respective Brake Controller's Tech Support folks. And/or, we each do our own Brake Controller to Brake Peddle Switch "capatibility" (sort of speaking) tests.

Hope this helps as well...

Found some more info extract about VBCM - Pin 30. re:

Thank you for contacting Technical Support. In response to your email, you can splice the red wire into the Body Control Module at pin location # 30. The Body Control Module is located on the left side of the dash roughly located above your left knee. The wire color you would splice into is colored “White”. I have also attached a technical bulletin that has pictures in the event you are unsure which wire to go to. If you have any questions or need further assistance feel free to contact us at (888) 785-5832.

Hope this helps as well...

I don't know if you have the tow package or not but there is supposed to be a 6-pin connector behind the driver back wheel to add a 4pin trailer connector.
I have checked my van fairly quickly tonight and cannot seem to locate it.
I am having the winter tires removed on Friday. The mechanic is a good friend of mine, I might be able to have a peek when the van is in the air.

If the connector is there, we might be able to use the brake light wire to connect to the electronic brake instead of using the pin in the BCM C2 connector.

Anyways, I will be poking more around the van over the weekend (Weather permitting).
I'll keep you posted on my progress.

Hi there thekingarthur.

My 09 Montana EWB has "NO" Tow Package option. I purposely looked for a '09 Montana 1SB with other safety upgrade options - "without" the factory Tow Package. If wondering, I've had too many previous bad experiences with "air shocks" and "air bags" on my previous vehicles. RE: They leak, they blow lines, they are expensive to repair, etc. Thus, I bought my own Timbren SES units (which is rubber blocks that are fitted within its rear coils) which are pure mechanical based. No air, no future troubles. And, much less expensive then $650 "towing option" - for air based load level system. For more details of this Timbren SES rear suspension upgrade product, surf: http://www.timbren.com/ses-van-suv.htm & http://www.timbren.com/timbren-application-guides/application-pdfs/GMRAZT.pdf If wondering, I had Timbren SES units in my previous van and "loved them since day 1". Thus, why I bought Timbren SES units for my new van as well.

I already bought my van's rear T-Connector. Actually, its a "twin" T-Connector wiring harness that is connected behind each tail light. For its install details on '06 van, surf: http://www.youtube.com/watch?v=ccMQ0-a12ls

I also bought a Hidden Hitch Class III/IV. This super strong hitch is expected to arrive within the next few days. To learn how to install it, surf: http://www.etrailer.com/tv-hitch-install-chevrolet-uplander.aspx

During the next week or so (when it stops raining in my woods), I plan to install 7-Pin Connector, its mounting bracket, approx 15ft of "twin" double coated 12 guage cabling (from rear hitch to front of vehicle) and its future Brake Controller. Also plan to install Circuit Breakers, Fuses and lots of pull ties. Within the 7-Pin Connector, it will have normal lights (from twin T-Connector harness), Brake Controller wire and 12V "+" live. This 12V "+" wire (off vehicle's accessory pole - thus, only active when ignition key is turned ON) will be used for a trickle charge wire - if attached trailer has its own onboard 12V battery.

For Plan A. For my future Brake Controller (probably a Husky model), I'm now thinking of finding the BCM's Pin 30 "white" wire (which is brake signal wire) and "double test it" with my volt meter. If it works as good as the Brake Controller Tech Support guy states it should, I will then follow it 12 inches away (from the BCM unit) and "tap" into it using appropriate sized press down clamp. re: http://www.sherco-auto.com/Resources/6127y.gif

If BCM - Pin 30 doesn't "test out" (using a Volt Meter tool) as expected, I'll probably install a simple 12V switch and custom bracket on its brake peddle. I can get a 12V push buttom type switch at my local Radio Shack store. And, being skilled with steel fabrication, I'd create my own switch mounting bracket as well. Same idea as http://www.roadmasterinc.com/pdf/751426.pdf This is my Plan B. But... Hoping to use Option A - if it Pin 30 "tests" with volt meter as expected.

I've not heard of an existing 6-pin that one can connect into. If there is a 6-pin connector, approciate if you can provide me the details. Might use this idea a Plan B and seperate brake switch as Plan C.

thanks for keeping us updated on your install ideas as well.

Well, we are in the same neck of the woods. I am in Gatineau.
After more research, it seems the connector under the van is only there if the tow package was purchased. Gotta change plans for the wire, we will have to go with the BCM wire.
I am transfering much of my tow equipment from my previous van, a 2000 Venture. Same frame so the hitch is compatible.
I am just waiting for the weather to cooperate to finalize the installation of the hitch, just need to drill out the last 2 holes.
For the brake control, I will use my Valley Journey HD that was previously installed on the other van. Do you have any recommendations for the 2-wire insulated cable you are going to run, looking for the best price.

For the moment, I am not planning on installing addition suspension equipment, didn't have any issues with a 7yo van last year so should be good with the new van.

What are you planning to pull with your van? I have a 3100lbs Coleman tent trailer.

.

Sounds like you have a "good upgrade plan" for your van as well.

For me, I might tow a small utility trailer "maybe" 3 times per year. Simple trailer runs to my local dump or to local dirt yard (for self landscaping tasks). Since my utility trailer already has electric brakes on it, I figure installing a Brake Controller in my new van is worth it. Especially since a small load of gravel or wet load of top soil becomes heavy. When a "loaded" trailer is more then 2,000 lbs (especially behind small vehicles - like a mini-van), I like having electric brakes on the trailer.

I'm also a believer that if one installs a Class II hitch, they should spend a few more dollars and install a stronger Class III hitch instead. Class III has a 2x2 receiver and if needed, I can easily slip-in receiver peddle bike T-Rack. And, a stronger Class III rack if better for the bigger road bounce bumps (when compared to a Class II hitch).

If someone asked me to describe my new van, I'd called it "my family touring van" that happens to have a hitch and brake controller on it. As a general statement, our new really isn't a Tow Vehicle (like your vehicle pulling a PUP trailer). But if needed, we can connect a trailer to it (just like our previous van).

Good luck on your "trailering upgrades" on your '07 van as well...

For "under vehicle" wire, I installed 2 x 10 guarge wires in my previous van. Got a 20+ foot roll of RED and 20+ foot roll of BLACK 10 guage automotive wire. Its expensive stuff but being 10 guage wire, I knew it would work. I then tapped both wires together (as in parallel together) to create 1 long 20 ft bundled cord, then fed this cord under my vehicle. I then Tie Wrapped it against brake lines and only had to install wire fasteners where Tie Wraps couldn't be use). Where needed, I installed plastic fasteners with self tapping steel screws, I then took some automotive tar and spread ontop of the fastener. Thus, reducing the risk of future rust - in that specific area (where dirt / salt might stick to the fastener). This worked great for my previous van.

For "under vehicle" wire in my NEW van, I'm going to buy the proper 2 x 12 guage "double covering" wire from my local RV dealer. Its a special 2 x 12 guage wire and its within another thick covering. If one feels this special wire with their fingers, it feels like a thick 'plastic covered' steel cable - like one would use on a small 12V power wench. My local RV guy explained its the only out door rated wire they install under their customer's Tow Vehicles. And yes, its much better (then my previously used) 2 x 10 guage wires taped together. As a suggestion, visit a few RV dealers in your area and ask if they sell this "special" under vehicle wire by the foot. My RV dealer charges $1.29 per foot. Think I'll buy 18 feet of it. What I don't use on this project, I can always use on a different wiring program.

Hope this helps others as well...

Today, I bought the "other needed stuff" I need at my local RV dealer. Luckily, the Sr. Tech Installer was at the customer area front desk - having a break with the Counter Sales guy. The Tech Installer told me that for my Montana van, he finds the "white wire" (from BCM - Pin 30) and follows it down to the lower LEFT foot side panel cavity area. (The left foot plastic panel is removed first). In this location, he installs a simple "press - together" TAP. Wraps some electrical tape round the tap connector and puts the plastic panel back on. Very simple install and DOES work on an '08 Montana van (that he did 2 days ago). And, he also confirmed the Husky brake controller (the one I had my eyes on) will work on this white wire as well.

Hope this confirmation on '08 Montana van helps in your '07 Uplander install...

http://www.marksrv.com/wiring.htm This site has some diagrams.
Normally a plug can be purchased for the brake controller and a plug is within 18inchs of the brake pedal. The parts also have a wiring diagram. Also search Champion trailer wiring diagrams.

Thanks for this URL. Lots of great info - that I plan to use within the next few days as well. Many thanks.

When it comes to Uplander/Montana vans (especially '07 - '09 models), I was told by 2 different Brake Controller companies and my local RV dealer NOT to connect to van's brake peddle switch (that is shown within generic wiring diagrams). The Uplander/Montana van is a "unique" vehicle. Thus, undocumented wire connection must be used instead. re: BCM - Pin 30 (white wire) into Brake Controller - instead of using traditional brake peddle switch tap. Other then this, all other wiring in the above URL site and included in Brake Controller documentation applies.

Just seen you updated (edited) your oringal post. If wondering, the Montana / Uplander is classified as a "van", and NOT as a truck. Thus, NO Brake Controller "special harness" adaptor cable is available. This was also confirmed from 2 different brake controller companies and my RV dealer. If you find such a "special" harness" cable, please provide its availability details, part number, URL, etc. Like many, I do NOT like manually taping into vehicle's factory wiring (or BCM output wiring) either. A simple "plug in" T-Connector / Adator harness wire would be very helpful. thanks.

.... Also search Champion trailer wiring diagrams.

Found: http://www.championtrailers.com/Electric%20brake%20control%20wiring.pdf

As seen within this PDF file, they show a Brake Peddle Switch in their diagram as well. Is this the diagram you were referring to?

A few moments ago, I "finally" completed the Husky Excursion Brake Controller ( http://www.huskytow.com/FTP/PDF/H-2-A_ELECTRICAL.pdf ) install in my '09 Montana van. With thekingarthur's provided BCM C2 Connector and Pin 30 location details (via direct Email attachments to me) I was able to connect my vehicle's BCM-C2-Pin 30 "white" wire to my Husky Brake Controller's RED wire. As planned, my Brake Controller install went "as planned". Slow progress (due to my first time learning curve) but in the end, the newly installed Brake Controller is now working great.

For lots of install pictures, surf:

http://s178.photobucket.com/albums/w251/Spike99-Pictures/Montana%20Van/?start=all&mediafilter=images

Note: Unfortunately, I did NOT take the extra time to test the "volt variance" states on this BCM's C2-Pin 30 "white" wire. I only tested my 12V "light probe" to confirm 12V present status when Brake Peddle Pressed and NOT pressed. Since +12V when brake peddle pressed, I didn't bother testing volt level for its peddle "unpressed" state.

Hope these addditional uploaded pictures help in your van's Brake Controller install as well....

Hi there...

Yes. I received your PM. Unfortunately, the email portal on this forum doesn't send .PDF file or other attachments. Thus, I sent you a PM (containing my direct email id). If you send me your email id (directly to my email id), I can sent you lots of pictures and other supporting details. Onr of those "this is how it worked for me" detailed info shares...

If wondering, the Brake Controller in my 2009 Montana van works great. Once installed and its wires wrapped with plastic loom, its been working great. Glad I "took the quality time" to install the electric Brake Controller in my new van.

Looking forward in receiving your direct email id (re: by sending email to my direct email id).

Thanks spike88, I sent you an e-mail right back.

Hi Corvetter.

Approx 1 hour ago, I sent the text info (and attachments) to your provided email id. If you do NOT receive my email text and several attachments soon, please advise. I will resend again. If wondering, the provided .PDF file (details on BCM C2) is most critical - for your needs.

Hope this helps your van's Brake Controller install task as well....

Hi guys.

Any chance I can get those diagrams sent to me as well? I'm trying to install and electric brake controller on a 2008 uplander next weekend, and I'm trying to get everything together for it.

Thanks!

Hi guys. Any chance I can get those diagrams sent to me as well? I'm trying to install and electric brake controller on a 2008 uplander next weekend, and I'm trying to get everything together for it. Thanks!

Hi there... A few moments ago, I emailed you 1 email msg with lots of URLs and 7 attachments. If you do NOT receive this email within the next few days, please send me another PM (Private Message).

Also... When gathering parts, remember to get a few 3/8" (or so) grommets as well. Like you, I proactively had all the electrical parts but didn't have the rubber grommet (for vehicle's firewall hole). Lesson learned as well...

When doing your Brake Controller install (from scratch method), remember that old racing turtle. re: "Pace yourself - slow and steady". If needed, take time breaks between each phase as well. re: Complete 7 pin install, then take a break, install 10 gauge wire under the vehicle, then take a time break. Slow and steady - since high quality within its install is very critical.

Hope this helps...
