I am a novice, replacing the engine wiring harness on a 69 chevelle. The harness I have is a reproduction of the original, which was for a points, coil etc. Can anybody help me with what mods are the required for electronic ignition?

Replace the resistance wire that went from coil+ to bulkhead with regular wire (use 12g) You can buy terminals and wire or buy a kit that has everything you need. Jegs and Year One sell kits.

Greg, thanks for the info.
