I have a 76 bronco with 302 aod. I put a power master starter and a one wire alternator on it. I did away with the ford starter solinoid and voltage regulator. I have a brand new ignition switch also. The starter engages when the switch is in the on position. Here’s the way I have it wired.
Big red positive Cable from battery to starter
Small wire from starter solinoid to the green wire with red stripe.
Small yellow wire to positive side of battery
Big black wire with red stripe to positive battery
Big black wire with yellow stripe to nothing.
Small red wire with blue stripe neutral safety
