Re: Wiring for Alternator, HEI, Lights, Fuel Pump
I'm running an HEI in my 63 with a Muncie 3 speed overdrive.
For the HEI, I removed the cloth covered resistor wire that goes from the firewall down to the starter and then back up to the coil. In its place, I ran a regular wire straight to the power plug on the HEI. That way I didn't have to add an extra relay or anything to power the HEI.
For the overdrive wiring, I used an additional relay to make the overdrive turn off the HEI ignition module just like turning the key off rather than grounding out the module like how the normal wiring grounded out the coil. That wiring is described in the link in my signature.
I'm no help on the alternator though because I still have the factory one in there
