Painless wire harness install (MORE PROGRESS)

With the factory switch, you connect the IGN1 and IGN2 together. Here's how they originally worked:

Mopar is the only US manufacturer that used this system, Ferd, GM, etc, all used an "I" contact on the relay/ solenoid to bypass the ballast for starting.

The reason you must interconnect them with no ballast is that MOST (all?) Mopar switches, the IGN1 (run) contact goes COLD during "start." This means that without IGN2 effective, it would never start, except by accident, sometimes letting off the starter it would catch.

I don't think Painless addresses this, which is irritating. As I said, they are showing a diode between the "start" wire and the ignition, which does work, although you have the additional drop of the diode junction.

Right on the NSS. Either of the "push on" relay terminals goes to the center of the NSS. The remaining relay "push on" terminal goes to the start contact of the IGN switch.

How big is your alternator, how big is the charging wire, and how is it routed?
