I can't seem to find the tach wire on my 2001 GMC yukon with the 5.3L V8 in it. All the places I have checked said that it was a white wire going into the ECM but I've tried both white wires that I saw and neither one was the right one. Anybody know where it is at for sure and/or have any pics of it?

Use the white wire at the instrument cluster. It is easier to get to and is protected from the elements.
