Found this great post with actual PCM pinouts to debug my cruise surging and AC craziness.


I can guess, but not sure what YE, BU-WH and VT-OG are for pins 16,17 and 18.

Btw, hopeful for solution since this close group of pins is related to my exact problems!

YE=yellow, BU-WH=blue with a white trace, VT-OG= violet with an orange trace, after 33 years as a Ford technician you learn these things :) the problem is Ford is using a lot 22-gauge wires now a days and it's getting tough for my 60-year-old eyes to see the trace colors!!

Thank you and I hear you! I'm closing in on 65 and up to power 2.5 on what my Dad use to call "Dime store glasses" ;-)

Only 2.0 for me :) same on the cheap glasses I have pairs of them all over the place I even have my wife carry a very small pair for me in her purse in case I forget mine.

It's also harder to decipher them if your lighting is low CRI, LED or fluorescent based.

Hell it's getting to the point that I can't tell which battery cable is positive without a 1000W halogen light :banghead:

I already ran into one problem. Solid yellow wire supposed to be on AC plug, but I found it in on the TPS (throttle position sensor).
Maybe TPS notifying computer at WOT to turn off AC?
