4L60E wiring...
I followed the diagram here:

But then the nice guy that sold me the ad on harness sends me a different diagram!
The harness is from an "F body" he said, and I am sure he is correct.
There is a difference in wire positions, as well as some color differences. There was a purple wire in pin 34 on C1, and 33 was empty. Looking at everything I have, purple belongs in 33, and the new white wire in 34. Maybe Bill goofed up?
Anyways, I am after an accurate diagram for my application and transmission plug pretty please! There is also a yellow/black wire with a spade terminal on it, and one with a PCM connector on it....talk about lost.
If I have to chase every wire, I am tempted to just buy a OEM harness used and make the thing myself, more so after catching a miss placed wire it appears. The rig ran before, but the trans controls were removed from the PCM, which have now been added back along with a tune.
Not helping with it being a heat wave here in Mo and the shop ac barely keeping up neither I guess....

There is a pink that is voltage into the trans, but I think that is supposed to go to another connector, will look at connector views later.
Still a yellow/black with a spade terminal on it, which confuses me....
Oh well.
Cheers
