Or do I still have to run another wire to the coil to get power while cranking also?

While in "start", the ignition switch shuts off power to the pink wire terminal and sends that power to the starter solenoid to energize it. Which in turn takes Battery power and sends it to both the starter AND the brown wire back up to the coil. This is how the coil gets a full 12V during Start. So leave the brown wire in tact.

Okay. Yeah I just looked when I got home and noticed the brown wire and pink wire run into the same connection on the engine side of the firewall. Thanks

Hi, I know this is an old thread but thought I’d chime in for those that want an alternative if it works for them. I left the resistor wire and under dash wiring undisturbed. I took the ignition wire from my starter solenoid and spliced it into my keyed on wire that turns my alternator on. Works like a charm.
I did add a diode in case my alt ever ***** up and somehow backfeeds power into the circuit which might make my engine not feel like shutting off with the key. But as it is, it would work just as well without the diode.
13-14 volts at the HEI. Works great for me.
