I found out its on the driver side top of the trans 2 wire plug thanks will check it out in morning

I wonder if my 3500 would have one, it doesn't have a backup light in the tail light housing I don't think. mines an all red Sport model. Maybe they just did it w this model. There are times. when I could use some light back there. I'd could use a setup like Michael has! Dave

back up lights have been around so long i just figured they were mandantory on a vehicle. icant remember anyone ever checking mine duriing a safety inspection. but some of those inspections are a joke anyway.

Backup lights were not standard equipment until the 60's. My 57 truck doesn't have them.

--- Update to the previous post...

Yes... The 2 pin switch on the top of the trans shift tower is the reverse switch. I runs back to the tail lights supplying power for all backup lighting and other options... If I remember right Black/Violet wire is the one your chasing...

Thanks!

So I unplugged and plugged it back in today and nothing changed I Will test the wires tomorrow and make sure I need a new one Do I need a special socket to get it off ? anything I should look for before taking it of ?

Probe the socket of the switch with a test light and check and see if there is power on one side. Then using a piece of wire and bridge across bothe pins and see if they light up with the key on. This will test to see if the light are good and if there is indeed power ther at the switch..
