My reverse light stays on all the time.
I did the wiring according to the manual.
Where have I gone wrong here?
thanks
mike

Automatic or manual? Maybe you reverse switch is bad

I was going to suggest the same.

Are your backup lights functioning correctly when you engage the trans into reverse?

Good call. See if the reverse lights
outside the car come on. I just had mine apart
in the spring. Also, make sure the switch is good, and the correct one for your car. A guy
at NAPA sold me the wrong one which I had to
return for what they had listed as a wrong item.

it's a 70 A Body 4 Speed. Back up lights stay off until I put it in reverse. Work just like they're supposed to. Could there some kind of ground I'm missing?

Maybe a short somewhere? A few years ago the wire going to my trans. on my Road Runner managed to come out of the retaining clip and make contact with a hot exhaust pipe when I was on the freeway. The reverse light came on and it stayed on until I discovered the wire was shorted on the exhaust pipe.

I am guessing it's a similar circuit to my A body.
The dash mounted light has a single wire feeding it.
Thats the power in, the other part of the circuit is
made by the ground on the dash. I'd trace down that
single wire to make sure it goes where it's supposed to.

My car had some really bad amateur wiring done on it. Took a long time to fix. Dome lights came on
with brakes etc. It was a mess. Hang in there and
take it one wire at a time.

Light on dash must be wired wrong. Both lights are operated off the one switch on trans.

Thanks for the input. I'll pull it all apart, re-install everything and see if that does anything.

Double check the position of the white/black wire running from the light into the bulkhead connector, and make sure it's located in the proper cavity.

If the dash reverse light illuminates, you know it's grounding, so the problem is in the wire which feeds power to the light.

This setup was removed from a '76 Duster 4-speed car:
