dwlee Posted March 15, 2016 Share Posted March 15, 2016 Here you go. I've include both the loom diagram and the wiring diagram for the 73/74. Note the some 75 and newer GTOs are a little different in places than the earlier cars. Quote Link to comment Share on other sites More sharing options...

dwlee Posted March 15, 2016 Share Posted March 15, 2016 Those images are just thumbnail links to the originals, which are quite large, so click on them and save the images. I suggest you print them out and tape them together to get one big wiring diagram. Key for the wire colours B = black L = blue W = white R = Red Y = yellow G = green BW would mean black with white stripe. etc The number before the colour code gives the size of the wire. From the ignition switch there should be 5 wires: L = is for the accessory circuit B = is the power feed to the ignition switch BW = the main ignition circuit BY = 2 wires, one goes the coil bi-passing the coil resistor when cranking. The other BY wire goes first to an inhibitor switch if the car is an automatic (bi-passed when car is manual), then to the starter solenoid.
