reverse light trailer hookup

how do you hook up the reverse lights to the trailer connecters?
all i see are the yellow green and brown wires. nothing else the could be the reverse.
am i stupid and missing something or what?
Thanks

None of our trailers have ever had reverse lights.

I've never seen a trailer with reverse lights either.

when i was looking up the wiring code for the standard circular connection pinout (standard 8 wire i think) there was pinning for reverse lights, though i didn't use that wire.

yeah the wiring for the connector said reverse lights and i had never seen it on a trailer either but figured id hook it up. als there is no reverse wire on the truck either. so if i want to hook up some bigger reverse lights cant. but anyways thats what i thught.

I guess we have a wire on the boat trailers that activates a soleniod to disengage the brakes when you are backing up, and that is hooked to the reverse wire of the truck.

See if this helps.



I believe it is the blue wire #2 terminal, use a test light to double check.

If you want to run some sort of reverse light you'll have to run the wiring for such from the front to the rear of the trailer. You'll have to be carefull how much of a load you put on it, because the truck wiring isn't made to handle a huge load. On your truck your just piggybacking off the stock wiring system. Some of the newer trucks have dedicated wiring just for the trailer, therefore can handle a little more load.

Or go really trick and use the truck's reverse wire to run a relay that gets its main power from the trailer brake harness.

^ ok so thats the thing which wire on the truck is the reverse wire?

Thanks

That's exactly what I was thinking.

On the harness that has the 4 pin flat connector at the end of the driver's side frame rail...brown is taillights, yellow is left turn/brake, then there's two greens - a dark and a light. I always mix them up in my mind but some really quick work with a test light will show you which is which. I'm pretty sure dark green is right turn/brake, and the light green will be reverse. The ground for the taillights is not on this harness; it comes from the taillight circuit boards and screws to the frame at the rear.

So unhook that connector, turn on your right turn signal, and use a test light to see which green it is. Then the other green is your reverse lights.
