The way I did mine, was remove the original resistor wire from the engine side of the bulkhead connector on the firewall, and replace it with a 12 gauge pink wire connected
to the BATT terminal on the HEI. The wire from the ignition switch to the bulkhead connector on the dash side of he firewall is already a 12 gauge pink wire. This will allow you to run the wire in the stock location and look like a factory installation. You will need a Packard 56 connector, can't remember if it's male or female, for 12 gauge wire. I got mine from the local NAPA store.
