I own a 67 camaro with a 230 and I bought a 18 circuit wiring harness. Ever since I installed it my generator light is turned "ON" on the ACC position and off on the "ON" position. The charging system is fine and I installed a new ignition switch, alternator and external regulator but the problem continues. I had this same harness on a previous camaro and there were no problems. The wires on the bacl of the ignition switch are as follows: red-battery, purple-SOL., green-ground, orange & pink wires-ign., brown-ACC. I triple checked all the connections, there were no burned fuses. The Painless wiring tech was to no help. Any help or comments would be appreciated.
