2004 laredo IAC/PCM issue.
I just recently picked up a 2004 jeep laredo with the check engine light and the error code 'p0505' which I assumed would be a simple fix, picked up a new IAC, dropped it in and started the jeep. The idle went from about 700rpm to 1,500(700 being the old iac). So i double checked the old one and noticed that the little piston was 'open' quite aways. So I dropped it back in and the idle went down, so I checked the wires and the left/right wires on the edges of the plug have no power. Now before I go and think about picking up a new PCM, I'd like to at least check the wiring at the plug to the pcm for power (to see if the power wire is damaged)
So, my question is: Does anyone have/know where I can find a diagram for the pcm? (or can just show me which wire cluster has the IAC's wires)
