Starting system wiring
This a morphed diagram and DOES NOT show the bypass wire. Wire at top right labeled "existing wire" is your "run" from the key, IGN1
The IGN2 bypass wire goes from the key to the coil + side of the ballast AKA the bottom of the ballast in this photo. Once again, this would be the same for either points or ECU
Starter relay. Get one that is application for your rig, and if you have an automatic, get an automatic. Other than mounting bracket, they are pretty much same up into '70's
The big stud goes to battery and is used as a junction point, but it internally connects to on relay contact.
The big "square screw" needs a no12 or better no10 from it to the starter solenoid
Either of the small push on "flag" terminals goes to the "start" terminal of the key. The remaining one, if auto, goes to the center term of the neutral switch.
If you have a stick, either ground the remaining flag terminal, or if you got a "stick" relay for 69/ earlier, that one will be grounded to the relay case. In that instance the relay case MUST be grounded.
