HEI Install... Resistor & ECU Bypass. HELP!

Lost you on the Ford solenoid. Chrysler starters have an integral solenoid, so why would you need that? If you want to change the Mopar starter relay, any standard auto 30 A relay works, which is what they use in later vehicles. Just wire the NSS in the coil- leg (pin 85 usually).
