Mopar/GM HEI wiring diagram using a bosch relay

All,

I used the stock Blu/Brn from the dist block combined to trigger the relay position 86 during both crank and ign power on with the key, 12v 10 gage from the battery to 30, position 87 to the HEI, position 85 to a new clean firewall ground location.

FYI,
Marion
