2005 GTO wiring question
I'm putting an 05 GTO drivetrain into a 1959 impala. I'm in the process of converting the original harness. Going well but I do have one question. Both the ECM and TCM have a yellow wire labelled accessory voltage. I find the double relay set up feeding this circuit a little confusing. Is it an accessory voltage feed from the ignition switch and does it need to be connected on a swap?
Thanks in advance!
The GM factory service manual for that car is available here:
