4l80e External Plugs
Anyone have a diagram/picture of what each of the plugs that are external on the 4l80e transmission? I color coded the plugs red and the wiring harness pins blue to make it easier to reference. This transmission is mated up to a LQ9 motor/wiring harness. I know the big round is is the main plug and I believe one of them is a speed sensor (#4 wire and #5 plug), can anyone tell me what the other plugs are used?

Pic quality is a little off, but from what I can see, your #6 wire goes into youre #3 plug. #2 and #3 are your PRNDL and neutral safety. 1 is a speed sensor. Looks like you are missing 2 connectors.

Okay thank you. I am swapping this in my old nova. Do I need any others besides the main plug and either input or output speed sensor? Guessing I need the output? Can I just cap the other plugs and not use them??

Zane, I have tried to plug #6 into #3 but it's not the same plug type. Keep in mind the lq9 motor has a 4l60e and not a 80 from the factory. That might be why I'm missing some plugs
