03 T&C P0508 IAC code

just wondering if anyone had an ECM pinout to a 2003 T&C 3.8L FWD

I have a P0508 IAC code, but I suspect a wiring problem.

I tried a donor computer, and an IAC motor from a good running van, still has same code.

Thank you!!

Also the vehicle does NOT idle, with the P0508 code.

inspect the wiring harness near the bellhousing and exhaust area...

Looks like no pinout. Do it the old fasion way. Match up wire IDs at either end. Might get lucky if they don't change midway.
