If searched on WKJeeps, but I can't locate the diagram. I'm trying to find out which wires in the harness are the signal wires from both front O2 sensors. The PTFC instructions state pins 31 and 33 are the correct ones for an '08 5.7, but I need to confirm for an '06 6.1. I don't want to assume anything when it comes to wiring. :)

hope this helps Ant.

sorry I had the pins backwards! fixed now..

just in case, here is a link to a mopar site has every connector pinout and diagram

http://dto.vftis.com/mopar/platform_select.asp?return=new

^ some times it wont show some connectors! I ran in to that many of times...but good info ....I forgot about that one...lol I did it the hard way in dealer connect:)

Thanks guys! I'd rather not crawl under the Jeep and tap into the wires there, but that might be the best approach. :)

NO problem....good luck on your quest on whatever your doing...:)

mana can anyone hit dealer connect?? or only dealers.....

Should be only dealers! ;)

I just over to the referenced site and confirmed the pins connections are the same, so I should be good to go. Time to go rip apart the PCM harnesses. :)

good luck ant !

Awesome Ant. doing it the clean way! :)

This is what I got from my program when I enter 2006 Jeep Truck Grand Cherokee 4WD SRT-8 V8-6.1L VIN 3

^^^^ I having a few issues, so thanks for posting the chart. :)

No problem. I am new here but I intend to keep checking back so let me know if there is anything else you need and I'll post it if I got it.

It's all good, just remember the SRT doesn't have a C4 PCM connector.
Just C1-C3. C4 is for the 5.7L down. Diesel WK doesn't either but thats immaterial...

I was wondering why there was no C4 on the back of the PCM. Now I know.

I'm awaiting a call, and at that point I guess I'm back to pulling apart the harness. :)

It is very important to makes sure you have the exact drawing for your year and make.

If you notice in the drawing, for a 5.7 it has the down stream O2 signals on C1 BUT it has the upstream return on pin 32 of the C1 connector inbetween the downstream signal leads.

Looking at C2, it is reversed (this is on the 5.7)

When I look at "most" 6.1 drawings, they have the Upstream signal leads on pin connector C2 pin 31 and pin 33 AND the upstream return on C2 pin 32, meaning all leads are on connector C2. This would be the logical layout whereas the 5.7 drawing seems backwards with the signals on C2 and the return on C1.

Have to love Chrysler wiring schemes.

The drawings posted don't mention the 6.1 upstream return on C2, so it looks as if it is missing.

Well that was what I get when I enter the SRT8. Sorry if it is not exact. :confused:

Pin 31 and 33 on C2 are correct, it's the Upstream Return signal that wasn't. Tim at NCTS was able to determine it was located on C2 also, Pin 32. Thanks anyway, guys. :)

mana can anyone hit dealer connect?? or only dealers.....

i have a dealerconnect login, as i work for a dealer. if you need anything feel free to ask.

Can anybody get me a diagram for the a 2007 srt8 jeep, it would be greatly appreciated!!
