Fire in the Hole

67Dart273,
That trailer connector is the hardware store connector I was referring to (found on appliances too). If you look close, you'll see that the male pin is shorter than in the Mopar distributor connector and thus won't make a solid connection. I suspect that is a problem for many owners since I found a similar short connector on a Mopar pickup I bought from rockauto. I bought 2 from rock at the same time (was cheap) and found one was correct and the other short. Of course I only figured this out after realizing an erratic connection while testing my HEI setup by spinning the distributor.

With the junkyard grab I suggested, all you must custom wire is the distributor plug also. The cable from module to coil is factory GM and not inside another harness.

The ClassicHEI kit does not show the distributor connector on the car side. I am guessing you cut the one off your harness, but pre-73 owners would not have that, and points people would be a big market for the kit. I had a 74 slant harness to rob.
