Deciphering wire color abbreviations ?

[Ruddy]

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

The correct wire on the PCM?

I'm getting codes P0446 and P1633 about which this post and this post say check fuse 24, which I did and it's OK, and I thought that cured the problem, but it turns out it takes a bit for the CEL to come on so I still have the problem. There is 12V at the fuse and the fuse is good. So next...

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

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?
