PCM pin out info (Updated 7-27-11)

Doing a SRT-4 Motor swap into your Neon, maybe even a 2.4... have questions about it, what you'll need or what issues you'll run into? Answers can be found in here.

PCM pin out info (Updated 7-27-11)

Post by Danteneon » Fri Aug 14, 2009 6:39 pm

I have received a few requests for the differences in the PCM wiring between the 2.0 and the 2.4 (as well as manual to ATX and R/T to non). This post will illustrate the differences.

I used the 2004 NGC and the 2002 JTEC for reference, but there were very few changes from 03-05 (NGC) and 00-02 (JTEC). As I sort out the post I will note any changes.

*Update 7/27/11* Per request, I have added the different pin-outs for the JTEC PT Cruiser.

Ok, here we go...

I bought an 03 FSM since there are differences between 03 and 04/05 C2 connectors and 03 has C101 and C102 connectors, which were replaced with just the 1 C101 connector for 04/05. I'm going to post what I found since I desperately needed this info for my 5 speed, mag swap on my 05 which has a hodge podge of wiring. 05 MTX sxt bay harness with circuits added to PDC for MTV relay/fuse, and 03 R/T engine harness. As stated above the engine harness had a C101 and C102 connectors, the bay harness just had 1 so I had to make it work.... hopefully it will.


C2 pinout changes for 03:

11.....K14 18LG/BR........INJECTOR CONTROL NO. 4 (04 colors: LB/BR)
16.....K200 BR/WT (04 colors: VT/OR)
28.....K961 18BR/VT......IAC RETURN (04 colors: BR/VT)
32.....K904 18BR/OR.....O2 RETURN **R/T ONLY, NON R/T SAME AS ABOVE 04** (03 non R/T & 04 colors: DB/DG)




Connectors below aren't at the PCM, but they are for the engine bay/engine harness, and I think its useful info to put here as this changed between 03 and 04/05 as well:
