Doesn't YO sell a harness with the electronic conversion? I think it is basically the same harness. When I have the time, guess I'll have to check with them.
most of the harnesses posted in this thread are from YO! M&H sells direct to YO.

I see the ground. Is that a "J" clip or something that the screw screws into? Looks like some sort of sheet metal screw. Thanks

Interesting approach to the wiring harness problem - nothing is labeled. I took a different cut at it over the last year. I have the shop manuals for both 71 and 72. I bought the following harnesses for my 71 GTX with 4 BBL and electronic ignition:

Dash
Engine (modified for electronic ignition)
Forward lighting
Rear Lighting (This harness itself does not connect to much of the rear lighting except the left side marker. There is another harness that plugs into it and picks up the tail lighting and RH marker. Nobody seems to make that one.)

Anyway, using the electrical schematics I made a sort of drawing of each harness, and annotated them according to the notation used in the schematics, which gives wire number, wire gauge, and color. Mostly, I left out the gauge, unless it was large wire. They're color coded, and a key is included on the dash harness drawing.

The people who drew these schematics, especially the IP schematic, weren't overly concerned about making them easy to follow.

Myb drawings are multiple pages. I scanned them to create PDF files for each. Can't attach, but would be happy to send to anyone who wants them. PM me.

Also, if anyone needs any schematics for 71 or 72, PM me and I'll get it to you.

Kind of reviving an old post but, has anyone found the rest of the rear lamp harness or who makes it? I have the M&H Rear Lamp Harness but can't find the brake lights, backup lights and right side marker light.
