Neutral Safety Switch

First of all, let me apologize for my earlier response. I don't know why but I was thinking that there was continuity through the neutral switch but the Mopar 3-terminal switch is not that way. Thank you, Bill.

Bill's description to which you responded above is correct if you have your system wired like figure 7 on page 19. You do not need to add another relay.

Replace the ground on the start switch with 12v power with ignition on.

The other side of the starter switch goes to relay terminal 86. (Bosch type relay.) You should get power through the switch when the switch is on and ignition is on.

Relay terminal 85 to the center pin of the 3-terminal neutral switch. At this point with the ignition on when you operate the start switch the relay should click if the trans is in Park or Neutral if the neutral switch is good.

Relay terminal 87 to the starter solenoid.

Relay terminal 30 to 12v battery power.

Do one step at a time. Test each part of the circuit as you finish it. You will get there.
