Resistor wire on a 68?

[1968ChevyC30]

Having spent several hours scratching my head over why my new MSD #8360 "ready to run" distributor and MSD #8202 coil won't operate properly with my freshly built 327. I have spoken with MSD Tech as well as gone over the wiring diagrams, and remain baffled as to why this distributor won't work. As a test, I installed a used Accel electronic distributor without a ballast resistor using the MSD #8202 coil and all worked fine. I also went so far as to obtain another new MSD #8360 distributor only to have the same problem as with the first one. MSD states that a ballast resistor isn't used with their setup, yet the Accel unit requires one. This leads me to believe there is a resistor wire within the engine harness that I can't find within the diagrams I have. Can any of you offer any assistance with my dilema? Thanks in advance.
