I like to install a relay on the 12V ignition wire. The key closes the relay which connects the HEI BAT terminal through 10 GA wire to the battery positive post. This allows you to keep your wiring from key to distributor, reduces total current draw through the ignition switch, and isolates the HEI power lead to eliminate engine run-on from reverse current leakage through the alternator.
