So here’s the short story....
I have a 1985 GT that I’m rewiring using the Ron Francis Express Wiring setup.
Specs-
Car 130A alternator and harness was setup for it by the folks at Ron Francis.
The MSD system is distributor, blaster coil, 6AL box, and tach adapter.
I have almost all of the wires for both pigtails on the cluster labeled with just a few questions.
Wires in question below:
-Black/Green 12v IVR wire - No idea what this goes to or what goes to it. It’s a solid core/single strand wire. Do I just give it a 12v source? That’s what makes most sense to me but I want to verify before I go hook up 12v to something I know very little about.
-Red/Orange and Yellow/LT. Green - These appears to come from the start/charge system and power distribution and go to the Ammeter.
-Dark Green/Yellow - Tach/coil negative, while in most cases I would know exactly what to do with this, I have no clue how this ties into the MSD tach adapter.
I’ve looked at the MSD diagrams and just can’t seem to make heads or tails of where the above listed wires go when using the tach adapter.
Any and all help you have would be greatly appreciated. Wiring is not my area of expertise and this is the last little bit I have to get figured out to make the car road worthy.
Thanks in advance!
