I am in the process of completely rewiring a 1971 Road Runner using an American Auto-wire harness kit. I have found a few issues with the kit but mostly, in the wiring schematics they provide but so far have been able to work around them by using other schematics to piece together the puzzle. HOWEVER........I have not been able to locate any schematics that show the tach wiring for the rallye cluster. I know one of the wires is from the neg side of the coil, but what is the other one for and which one is which?? This is just the way I found the wiring and is one of the main reasons for the rewire. ![[Linked Image]](http://pic100.picturetrail.com/VOL264/2074170/24771117/414290625.jpg)

The dark blue on top is ACC 12v feed and the lower one is the tach feed to the coil.

I have that page(S) bookmarks and checked them before posting. It only shows me two schematics for the 1971 GTX, Road Runner etc. (sheet A and B) and neither one of them shows the tach wiring for a rallye cluster. What am I missing???
