Engine test stand wiring??
The diagram I likely referred to is the popular conversion one, where it calls out a wire going to the "start relay." That is the part that is wrong. If you are going to run your Mopar system the problem is that in a Mopar CAR the ignition switch provides the ballast bypass during starting. On stuff like Ford/ GM, the ballast bypass was done on the starter solenoid.
There are several ways around this problem. . . . . . .if you are using a start button instead of a key switch, you can
1...install a relay for the bypass circuit
2...use a fairly large diode to feed the bypass circuit
3...use "dual" start switches and just push them simultaneously, and use the second switch for the ballast bypass
So you see, LOL "it aint" that simple, stand by.........
This is likely the "root source" of the wrong diagram

NOTICE SAYS "yellow wire to start relay." WHY this is wrong. On an earlier stick car (no clutch safety switch) or on any automatic car with the shifter in neutral or park, the start relay will have a GROUND path. When the engine is running, with the key in the run position, the yellow wire WILL BE BACKFED through the coil resistor, attempting to "fire" the start relay!!!! This can, in some cases cause the start relay to pull in and energize the starter, or if not the grounded start relay LOADS THE coil circuit from the resistor.
THAT CIRCUIT IS INCORRECT!!
