Soldering, I hate T-Taps with a passion

Forget what I said before, you have a second option. My reason for reverse was that it sits on ground when inactive, but in that list you published in the first post it shows a RED cable as the neutral safety switch. Connect the black white to this.  Verify this i.e. red wire goes to ground if gearshift is in neutral or park, forget the toggle switch it's not needed.
