OK I was not thinking for some reason OF COURSE the Mopar starter solenoid will only have one small terminal LOL
I can't read that diagram very well it appears that the yellow "run" goes straight to the coil? If so, and if you need a ballast (and you do for the Mopar system) then that yellow would go to the "switch" end of the ballast just like Mopar. Then for the bypass circuit you can do as I mentioned.......either run a separate relay like a Bosch to operate with the starter solenoid, and run "straight" 12V to the coil+, or run a diode from the solenoid S terminal to coil +
