So i've been chasing a grinding noise in my Explorer swap as chronicled here. I've narrowed it down to my mini pmgr starter trying to engage anytime I shift it across P or N. I was testing it yesterday and I believe I finally killed my ignition switch as my engine suddenly shut down and won't turn over. While I wait for my new ignition switch to arrive, i've been reviewing all of my wiring.
Here is how I have my starter solenoid wired (per diagrams):
And here is how I have my mini pmgr starter wired:
Which both look correct per the diagrams I have reviewed.
Which leads me to believe my issue is with my ignition switch. I originally had my painless harness wired up to the ignition switch. When I added EFIGuy's harness, I removed the #919 wire and replaced it with EFIGuy's pink wire.. but according to the ignition switch diagram I found from a Viperwolf post, that terminal is +12v in run?? Which leads me to believe that i'm constantly sending 12v to the PCM and hence to the starter? Is this the source of my grinding noise from the starter trying to engage anytime it's not in R/D (since NSS would block it?)
