ignition problems

I bought a 64 and 65 Mopar in the last few years and both had the wiring harnesses hacked up. It seems few people know how to wire correctly, including many "professional" mechanics. One fool installed an electric fan (no mechanical fan) and ran ~20 awg wire ~8 ft to power it off the ign wire (twisted together and taped). The factory wires out of the fan are ~12 awg, which should have been a tip.

To answer your question. Lose the toggle and replace your ignition switch. I got one recently for ~$8 at rockauto. You do need to swap your key cylinder, but that is easy (push in release w/ paper clip w/ key in correct position).

To answer your 2nd question, it kind of does matter where the voltage regulator gets its 12 V. Think of that as the "sense wire". It adjusts the alternator to regulate the sensed location to its preset (~14 V). You do want that to be a switched ignition source, otherwise Vreg will run down your battery when sitting. I would pick the most upstream position, which is where the ign wire first lands after coming out of the bulkhead before branching to other devices. In my 65, that spot was the terminal where ign feeds the ballast resistor. I re-wired mine with an under-hood ign relay, so wired Vreg to the relay output.
