Just figured out photos so here's an annotated photo of my wiring. Do I have this right?



1. Relay post # 85 to 12v switched source at blue wire connector for ballast resistor.
2. Relay post # 30 to alternator output stud through 15A fuse.
3. Relay post # 87 to splice joining "B" terminal on module and coil + terminal.
4. "C" terminal on module to coil - terminal.
5/6. "W" and "G" terminals on module to distributor pick up pigtail.
7. Relay post # 85 to ground through fender with star washers and bolt/nut. Cleaned fender to bare metal both sides at contact.
Module is grounded with mounting screw through fender with star washers and lock nut. Cleaned under side to bare metal. Applied thermal grease between module and aluminum mounting plate.

Is this right?

Apparently, the answe is yes. One thing to add though. You DO need a wire from the OEM coil + terminal and the HEI "B" terminal to your coil +. The original is necessary for the start/kill function of your ignition. Thanks to all!
