So, the trailer has no brake lights, or turn signals, just tail lights? Everything (all lights) on truck work ok? What do you have for trailer wiring hook up 4, 5, 6, or 7 way? There is no fuse, the lights all work off the tow vehicle lights, so if the tow vehicle lights all work properly, it's probably a wiring problem, such as bad grounds, loose connections, etc. Get a volt meter and check voltage at truck plug to see if power is getting that far. If truck plug in is ok, wiring problem is the trailer. Make sure all grounds are tight and rust free, that's a common problem.

Where to find the wire going to the trailer towing plug for the braking.


As far as I know, your trailer towing package does not include a circuit for trailer braking. These packages normally only supply taillights, brake-lights, and turn signals.
RV sales and service dealerships should be able to help you.
God bless your efforts.

Where can i find a identification diagram for a fuse box on a 2007 dodge ram 1500?


Unless I'm mistaken, there is no fuse dedicated to the trailer lights - they're wired directly to the matching truck lights - the running lights & taillights should be wired directly to your truck's taillights.

Check your trailer wiring from the truck plug all the way back. I've seen lots of poor connections in the truck plug, as well as any of those squeeze splices you might have in your trailer. Look also at the ground wiring for your running lights.

I have a standard 4 flat trailer plug on my truck but my trailer plug is also a 4 flat plug but has two brown wires going to one prong. how do i hook them together to make all my lights on trailer work


The 4-wire flat plugs usually have a white (ground), green (right brake/turn) yellow (left brake/turn) and brown (taillights - left and right). If your brake and turn lights work but the taillights don't, check the plugs (trailer and truck sides) for corrosion, and chek both the trailer and truck wiring harnesses for chafed insulation and bare conductors on the brown wires. Likewiae if the taillights work and the brake/turn lights don't, perform the same checks on those wires. And last but not least, be sure that the white wires (truck and trailer) are grounded well to the truck body and trailer frame.

When applying the brakes the reverse lights come on and the interior turn signal indicators turn on.


Does your truck have trailer hitch wiring? That would be my first suspect area. Check trailer wiring plug for corrosion and shorting. 90% of GM truck taillight problems are related to trailer wiring.

When i hook my trailer to my 2002 ford superduty i have no running lights on trailer.brake and signal lights work fine.WHY?


Hello, if you only have taillights on the trailer and no side markers, check your bulbs first. The bright side is used for the Brakes and turn signals and the normal filament is used for the running lights.

If you use a test light you can find the pin on the connector which runs the Running lights. Sometimes the wiring harness will pick up the running lights off of the taillight in the bed of the truck. You would look for a wire going up into the taillight housing from the Trailer plug.

If you are the original owner of the truck there was a small package of Relays and wire ends that came in a plastic bag. It could be stored with the jack. This package had wire color information and instructions for Electric brakes. It also color-coded the Trailer plug-in socket as they use the extra pin holes for the Electric brakes. All the wires are discussed.

If an aftermarket unit was wired in the running light, the wires could be any color. The industry tried to put in a standard, but instructions still say if you don't have one color, its another. That is still vague.

My 1996 Toyota 4Runner is equipped with a factory tow package; however, I'm unable to locate the plug for trailer taillights.


If you don't have a 'plug' for the trailer taillights, then the trailer renter, like Uhaul, sells bulb adapters that hook into the tail brake and light lamps that can power the trailer taillights.

I remember, I had a 1980 Suburban that didn't have a 'compatible' plug, and that's the way we resolved the problem.

Good luck on this towing.

I hooked up my trailer lights everything works but my taillight


If you have access to a digital multimeter or test light, check if there is power going to the plug, if there is then maybe the trailer plug and the truck plug dont match up
