Engine Dyno Questions!
If you do not have a separate ignition harness to fit the box it might be simpler to "not" use the Mopar.
If you have an aftermarket ignition harness just pull it out and hook it up. You VERY LIKELY DO NOT HAVE a 5 pin box even if wired that way
Another way around the problem is to go down and buy a GM 4 pin HEI module. Scare up a small piece of aluminum for a heat sink and wire that up
If you look at the 4 vs 5 pin wiring, ONLY THE SECTION OF THE RESISTOR on the left has been eliminated and is not needed. If it "is there and wired" it will not hurt anything on a 4 pin box. The BOX MUST BE grounded. The "existing wire" labeled at top right is the 12V power.
Or wire up a GM 4 pin HEI module
The module has a locating "tit" on the mounting surface. You will either have to cut/ file that off, or drill a clearance hole in your mounting plate/ heat sink. The ground connection is one of the mounting holes. NOTE the diagram of the distributor hookup. They must not be reversed
