Check your receptacle with a test light, to find out if it's the truck or the trailer that's the problem. If you have power at the truck, then take your trailer rceptacle apart, and see what's going on in there. If you don't find it in the plug ins, just work your way back with a test light. Its corrosion or a broken wire somewhere. Wiring can drive you nuts.

Changed fuses fow tow connector. #3 and # 7. Now the left trailer light,signal, brake,etc works while only right tail light on trailer still works. On right side, the tail works, but not the brake,or...


I would recommend taking out the tail light. Get a test light, have an assantant step on brake. U will see the bulb in tailamp light up. Probe the wire w/your test lamp. That is brake wire. Repeat that process for blinker.. Drop down those two wires. Hook that to the same side on trailor. Repeat for left and you should be all set.

No left turn/brake light for trailer


In the Uk nearlly all trailor socket wiring is done from the rear light wiring of the towing vehicle so I suggest checking the wiring back from the trailor connection socket and also socket, it could be a broken or cut wire. Also will probably find your vehicle a control unit fitted the trailor socket which could also the problem. Find the pin outs for your turn signal on the socket and connect a bulb across this connection and the common earth to check its not a fault on your tralior.

Well for the camper there are for wires for the lights i have green wire that is the right turn signal and hooked it up on the right side to the green wire which is the right turn signal in the car then...


well, the following is the generic (standard) wiring for trailer plugs......

tail (clearance) = brown
left hand turn = yellow
right hand turn = green
stop (brake) = red
electric brakes = blue
earth = white

now, you said that you had connected green, yellow and brown, and white. which is all well and good, but you did not mention a red wire which would be for the brake lights.

I hope this helps, get back to me with more info to assist you.

I need to hook up a boat trailor Whats the color code for a 1995


I suspect that the 4 wire harness includes a ground, so you may not be able to connect both brake lights and turn signals, which are separate lamps on the pickup. You may need to get an adapter.

In any case, the color codes on the pickup are:

Tail lights -- pink/blue
Brake Lights -- green/yellow
Left turn signal -- gray/blue
Right turn signal -- gray/red
Ground -- black

the wire you maybe talking about could posibly be for the trailer brake controller, which you have to buy serperate i'm not to sure how much it will run you but i would look into that because that is what the extra wire is usually forwith the 7 prong trailer plugs

This sounds like some wires may not be connected or connected improperly.On this vehicle the wire colors are: Brown=parking lights,green=right turn/brake,yellow=left turn/brake. You will have to drop the spare tire to get a good look at these.
