Ah wait a middet, The only thing on the starter on a 59 or earlier six cylinder truck that is involved in the ignition is the resistor by pass stud on the switch.

That is to give you 12 volts to start with when you are cranking rather than the 6-9 (somewhere in there) volts you get on the coil side of the resistor or resistor wire.

HEI have to have 12 volts to fire good and if you connected the plug with the pink wire to the old ignition wire to the coil you aren't getting full voltage all the time.

with the Key on that plug that goes to the hei should have 12 volts all the time. You shouldn't have to use a bypass wire at all with the stomp starter.

A wiring diagram that 1project2many posted in 2017 in answer to a question shows the resistor in the wire to the coil. If you haven't I would bypass the original ignition wire all together and run the heavier wire for the HEI all the way to the switch or non fused pin that is powered when you have the key on in the fuse block if there is a fuse block.
