GM control module
There's a projection on the bottom, you must either drill a clearance hole or cut off the projection. Heat transfer compound "is recommended" but I don't use it. Mount it on some sort of small heat sink. Even a flat scrap of aluminum. Pay attention to the polarity of the pickup coil--it will screw up "rotor phasing" if you reverse the pickup, and cause rough running and crossfire, etc.
Bypass the ballast resistor so the coil and HEI get full battery voltage
