Back up light switch wiring
#1
Hey guys,

I was just looking through the hole in the transmission hump at the top of the shifter (4 speed manual) and I saw a gizmo with two spade connectors sticking out the top of it with nothing attached to it. I suspect this is the back up light switch. I've also got a pair of wires that are about the right length to reach. Both these wires are black and are inside a hard plastic shell rather than the usual electrical tape.

These wires go to a 2x2 connector located at the center of the firewall. These wires attach to 2 of these connections while the other two have a red jumper wire connecting them together.

Does this sound like the correct wires for the trans switch? My chilton manual doesn't have anything on this bit of wiring at all.

Thanks!

William

Yes, sounds correct
2 wires are for back up lights
the jumpered wires are for nutral safety switch on automatics

I had suspected that the extra two wires were for automatics.

That jumper wire is certainly made to order for a place to wire in an alarm system or hidden kill switch. That jumper is completing the starter relay circuit right?

Back in the 60's/70's guys would hook a toggle switch to the back up lights. When they went cruising and were looking for a drag they would turn on the back up lights and leave them on to signal they wanted to drag. Maybe that's why yours are disconnected! Biggrin

That is correct.
