Hot Rods Help Me Wire A Neutral Safety Switch On My 37 Chevy Coupe

I'm getting back to work on it. The car has a B&M Z Gate shifter hooked to a THM 350 transmission The neutral safety switch "switch" is there, but it was never wired by the PO. It works checking it with a continuity tester. It's a simple ON/OFF switch that is controlled by the position of the shift lever so it'll start in P or N.

I've pulled the ignition switch. Refer to the pictures.

I've got a BATT terminal, an IGN terminal, a ST terminal (solenoid) and an ACC terminal.

You can see a bunch of wires on the BATT terminal, one wire on the ST terminal, one on the ACC terminal, and one on the IGN terminal.

How do I wire this switch? Do I simply "break" the solenoid wire and wire the switch "between" the wires?

I'm electrically challenged.

TIA

Chuck

 

yes, you break the SOL wire and connect the ends to the C and NO terminals on the shifter switch.

make sure the switch is in the correct position to act as a neutral switch...not as a back up light switch..

 

Thanks, Squirrel. Worked like a charm. I rigged up the wiring with alligator clips and fired it up.

My concern was that when I "broke" the solenoid wire, I wouldn't get engine electrical power when I shifted to R, D, 2, or 1 since the switch was open, but everything works.

Now, back to work on the final wiring.
