I think I have excessive resistance in the K4 sensor ground circuit of my MAP sensor, but I'd rather not rip my entire wiring harness apart to find it. I think the Camshaft, Crank, TPS, and MAP sensors all share the same ground. Does anyone have a diagram of the PCM connector pins? Like something that shows which pin is for what, or even which pin is what color wire. There's a tool (special tool #8815-1) that tells you exactly what I need to know but I'd like to avoid spending $220 on a tool that I will use once in my life. The truck I'm working on is a 2006 Dodge quad cab 1500 4.7. Any help would be great, thanks!
or even better, take the time to click on the links in my signature and download the full service manual that will answer your original problem and more
I've already downloaded your 2006 Ram Service Manual (many thanks for listing all these manuals by the way! :-D) but after spending a few hours reading through it, I still found no cure for my problem. It is just not descriptive enough to help me troubleshoot this F#&@ing P.O.S. truck and it's cheaply made, shorted out wiring harness.

- you can get that info from identification for $20 for a monthly price
