Connector

What is this under the plactic cover right in front of the 3 plug wire going to the 3 back cylinders< well on or my wire are burnt and http://[under%20hood.jpg]/just holding by 2 wires treads so what is that connect called, i have a pic or it but i dont know how to put it on here

Where is the pic?

Just a guess but are the three wires purple, yellow and pink going to a connector on a bracket? If so that is for the front 02 sensor. Not good news.

Still no pic coming up...:dunno:

Well i dont know how to put them pic up< but the 1st 02 sensor is in the back of the engine< this connect is in the front or the engine and where the 3 wire comming from the oil pack< the connect is right there in front of those wire< so basicly its right by the coil pack under the cover on the GT grand Prix it like a 10 pin connector < i really didnt count them< but i will>> < on the buttom on the reply box it say insert image and then it says enter the URL or the image< where do i find the URL> i just cut and copy the image and paste it on the page but it didnt show as you see((((())))))It right in front of the front fuel rail over the the coil pack

OK now we are getting someplace. I thought you meant in the back of the engine. If the wiring connector is between the coil pack and alternator that goes to the MAP sensor. If it is the bigger connector close to the right side of the UIM Plenum then that is the joining connector for the coil packs and ignition control module. If it is the connector on the plastic cylinder looking part by the right side of the UIM that is the purge solenoid.

Can any of those cause the engine to mifire< obviously it comes from the PCm and i have the replaced the whole wire and pin ( the connector < its right behind a plastic piece and has a little tube running into the side of the throttle body

If it is the connector for the Coil Packs/ICM sure. The plastic piece with the vacuum line going back to the throttle body is the purge solenoid. But the purge solenoid does not normally cause a misfire. Just throw a code of maybe P0441.

But it sounds like the connector for Coil Packs/ICM so you may be onto something significant. Good luck!.

I see the purge solenoid at bottom of the pic and the connector behind it is the joining connector for the Coil Packs/ICM.

So is there anyway i cant replace that connetor with a new on without taking it to a dealership< i know that go to the pcm well at least the one that is burnt< and those pin i need they sell online< and all the dealership around here dont have them in stock> ( the pins the hook in the the PCM connector But all i really need is that connector< but do they just sell that connector< do you know the part number>

I'll check that part number for you when I get to work.

Alright i just need the connector peice i know the part number or the pin the goes into the PCM connector< but thanks

If you're referring to the 8 way connector behind the purge valve, the half to the right in the picture is part # PT444 (GM#12117271), and runs $35.59 (dealer retail $71.17). The half to the left, is part# PT443 (GM#12117270) and runs $35.56 (dealer retail $71.11).

With his luck it will probably be on the PCM feed side of the connector. But if it is the side to the ICM/Coil Packs/CKPS I wouldn't mess with just the connector. He could replace the complete Y wiring harness with connector intact. I see it only goes to the ICM/Coil Pack connector and the crank position sensor, therefore can be replaced in its entirety.

BTW - Something had to cause the wiring damage unless he did it accidently or unknowingly.

Sounds like a trip to the boneyard would be a lot cheaper to me.

Note: That Y wiring harness has the infamous single ground wire that connects to ground on the ICM/Coil Pack module.

Good point Bob.

yeah the burn is on the PCm side of the connector< i noticed it when i got my DHP PCM and i didnt know where it lead to into last week so its been like that for a while since feb 06/ so i'm tryin to replace it now< i dont know how it got that way or how long its been< I may have done something or have it been like that since i got the car in 03 < so i really need is the Connector and one wire that runs to the PCM with thoses Pins to put in the PCM connectors < it was only one wire Burnt like a orange/black wire it looks like>

Do you have a better pic showing the damage?

Where exactly is the damaged orange/black wire and how bad? Is it right at the connector or where the wiring comes in/out of the connector? You may be able to field fix it by repairing just the damaged portion of the wire.

Also, have you disconnected the connector and inspected for any damage, arcing at all pins? The connector has a safety tab that has to be removed first. I just cut mine off and trash it.

the Damage Goes from to PCM and leave a burn trail to the connector< I Wrapped some wire around it to Temp(replacement) intil i get the parts to do the repair But from the looks of it the connector inst damaged just the wire< i havent took it off< b/cuz i dont wanna damaged it anymore intil i get the parts to fix it you know< but the other side ot the connector isnt damaged at all<

How much of the orange/black wire coming out of the connector is undamaged or is it damaged right up to where it inserts into the connector?

Yeah its all the way to the connector< it was on holding together at the connect by two threads or wire< but i wrap it up with wire and electric tape it look new, but i know better. Like i said it just holding together so i can get the part< i'm going to change those plugs tomarrow> I got those wrenches you have but i guess the only prob now is the 100 deg heat tomarrow>

It is hard to say on the connector but you can dismantle it and possibly splice in a similar grade wire (range of 18 - 24 AWG). Either way when you get the new connector it will be a PITA. Instead of just one wire you will need to connect 7. Of the 8 pins, 7 are used.

I see you are in Dallas so the humidity will probably be bad. I'm in El Paso and we hit over 100 a few weeks ago but our humidity is 20% or less. Have fun and good luck.
