904 to A833 Neutral Safety Switch

Thanks everyone. I took the switch off of my clutch pedal before installing it. So, if I re-install the switch do I just run the heavy brown wire from the starter relay to it? Or, I guess I can just eliminate the heavy brown wire an live without the clutch switch like they did in 68.

Lordie. NO!!

Look at your starter relay. All early stick cars (before clutch switches in '70) had THREE terminals, and the relay coil was grounded by a big solder blob where the 4th terminal should be

All stick cars with clutch switches, and all automatic cars have a FOUR terminal starter relay.......two push ons and the big battery stud, and the square solenoid terminal.

One "push on" gets the yellow wire out of the bulkhead, which is your "start" signal from the ignition switch

The remaining push on terminal goes either to the NSS on the automatic, or to the clutch switch if used. If no clutch switch, just ground the second push on terminal.

The two terminals on the 4 speed are reverse lights, and 68? 69? later automatics ahve a 3 terminal NSS. The center pin is NSS, the two outer pins are reverse lights.



Big threaded stud is a battery junction point and one relay contact

Big "square" terminal runs down to the starter solenoid with a large gauge wire

Either of two "push on" terminals goes to the yellow "start"

Either ground the remaining "push on" or run it to your clutch switch.
