Speed sensor wire?

[skipnrocks]

I need to wire my gm 4l80e I have the plug but I'm not sure which wire should go and which side the plug? Does it matter?

I got it figured out. I found an online GM wiring diagram. And then made a best guess on the aftermarket one. Works great!

Good you figured it out. Did the wires end up specific or not matter?

 

[skipnrocks]

They are specific. On is a low voltage and has a black stripe and the other is a high voltage signal

Good deal. I'm running a dummy trans but this info could come in handy later on.
