Custom tach light??

[NuEra]

I was wondering if its possible to make a tachlight from a led light such as the vtec indicator on jdmfan.com. Basically what I mean is just a led light that turns on when I reach a certain rpm. Then wouldnt I need some kind of controler to adjust when it comes on? Do they make such a thing, is any of this possible?

[Shizzle123]

yea on most tachometers that you buy they have a lil circle light on the top which turns on when u hit the rpm u have set it to

[NuEra]

yeah but I mean can I use my own light? I dont want another tach other than my stock one so I just want to hook a led light up to some controler that I can set o turn on at certain rpm's.

i have no idea, but id say try asking somone who has a tach with a light, and see if you can figure out how it works.

ok, what do you think of this? I can buy an MSD rpm activated switch with a module kit and just connect it to a LED. It seems as though this set up will work, what do you think?

sounds good to me

I believe (correct me if I'm wrong), but I think RPM on the stock OEM tach is controlled by voltage. If so can't a voltage controlled switch be used to light the led running off of a relay? I to wanted to do this, but the only thing I could come up with was using one of those adjustable shift lights (seperate from a new tach) and soldering leads into the light socket connecting it to an LED somewhere in my dash and hide the controller somewhere else.

ok, here it is. I'm ordering an rpm activated switch, cheap but effective, you could by msd's but they require modules(more money), with this one I can adjust the rpm without anything extra. I'll just soder the led on and connect the wires. I'll let you know how it works out with pics, maybe.

P.S. what wire would I splice for the tach and where?, I have a 98 civic

Man!, this is just not working! There's so many things that are possibly wrong.

First off, Im not sure with the tach wire, I connected to the back of the gauge cluster, but Ive read stuff saying you need to connect under the hood. For this you need to get through the firewall, but I dont see any grommets.

Second, the 12v wire I connected to the power socket which I think is good. But before this, just to test it out, I spliced it to my indiglo gauges which are connected to the parking lights. When I took the splice out, the gauges stopped lighting, Great!! Now Im screwed, did I short circuit them or something, did the splice cut the wire??

Third, the RPM activated switch I bought is made by VDO from "Racer Parts Wholesale", I dont know how good that is, it looks cheap, it may not even work! Is there any way to test this?

Lastly, I dont know if I'm paranoid now or what, but it seems like my passenger side power window is going up slower and noisier than usual. Theres no way I could have caused that is there?

If you can help with anything or have any idea PLEASE post. Thank you so much.

My indiglos are definitely not working, I checked all the connections. What should I do? There's a white plastic piece on the power wire of the indiglos. I can see through it a little and it looks like theres a spring with space between it. I connected the wire that would have shorted it before it. Theres also a black box where all the wires derive from. Does anyone have an idea on how to fix it. If not, would the company exchange me another one for the product? Its made by Toucan Industries. Somebody HELP

if im readin this right then im guessing that the connection has been broken, perhaps by short circuiting??? you will have to replace the indiglo as you can probably guess. if it is meant to be there then yes, the splice could have cut the wire (if you must then you could try resoldering the wire or replacing it). VDO are a good company and make a lot of gauges, so i would think the switch will work ok. i think you're window going slower is probably just paranoia!! unfoirtunately i cant really help you fix of what you have told me, is it possible that you could post some annotated photos of the assembly? that would make it easier for us all to help you.

[NuEra]

yeah, ill get some pics up quickly.

[NuEra]

This is the white thing,

[NuEra]

Heres how I connect wires, by splicing, is this OK?
