i need help with wirin 72 gmc
i putting a new 21 circuit harness on my 72 gmc. A lot of the wires are diiferent. One of the wires that comes out of the fuse box says ignition coil. I don't think it goes to the coil because a wire that reads pos coil comes out the other end of the fuse. I tried hooking the one that says ignition coil up to the key swithch but all of those wires have to much juice and blow the 30 amp fuse. PLEASE HELP!!!!

Have you tested the two different wires for power from the ignition switch? Having power whether the key is on or off? |

You using American Autowire. If you are you can download it off the site. Who did you buy it from? I just did it a few months ago let me know if I can help. -J
