Success . I didn't think the 4 terminal ballast harness was used in '69. I'm assuming the 4 terminal ballast will plug in to the harness (has 2 double ends) only 1 way so that you are on the lowest ohm half of the ballast. As you researched the other side of the ballast is not used on a 4 pin ECU.
you sir are correct. 69 should be a 2 pin. but, don't we all tend to use what we got and make it work? that's half the fun!
