Not true. Look at 273's post. The wiring Joe gave is only for the 1-ballast type and would melt the ECU if the original one that needs the 2-ballast. As I said "more confusing".
Well Bill,looks like the original poster is working on a 67 with a you guessed it
2 prong ballast resistor. But you already knew that.So yes,Joes diagram is perfectly correct.
Its a 1 wire hook up.Turn the key on,find out which ballast wire is hot,hook the blue harness wire to it ....done. Not to complicated.
Dam......The sky isn't falling afterwards........:glasses7:
