Use a multi meter to find which pin has the power when the light is operating and match the trailer wire to that pin. There is a standard code for wiring trailer plugs but some people ignore it and then when different trailers are connected some items do not work.

SOURCE: LEFT TRAILER TURN SIGNAL DOES NOT WORK

I'd get a 12vdc test light if you don't have one already & start from plug, and keep probing back from there. It may be as simple as a bad connection under truck where joined into harness.

SOURCE: Only the left rear trailer light comes on when I apply the brakes.

I had the same problem with my 2002 Silverado last summer when I first bought my boat and was getting the trailer ready to go. Like an idiot, I rewired the boat trailer on that side before I decided to look at the owner's manual. The pickup has separate fuses for right and left side of trailer. They're located in the big box in the engine compartment. I replaced the 10 or 15 size fuse and haven't had a problem since. Hope this helps!

You may want to get a ground loop isolator or even cheaper. Go to radio shack and buy two 1amp diodes and put them on each turn signal wire. This will eliminate the problem. The diode will be black with a gray line. the line will go towards the trailer on each wire. this should take care of the problem.

SOURCE: No trailer right turn signal or brake light

Hey Boon,

The pinouts for a 7-way plug are as follows:
Seven wire Trailer plugs:

Horse, stock or utility trailers:

White = Ground - 1
Blue = Electric Brakes - 2
Brown = Tail and clearance lights - 3
Black = Battery, aux power - 4
Yellow = Left turn/Brake - 5
Green = Right turn Brake - 6
Orange or Purple (not both) = Auxilliary or Reverse - 7

Recreational Vehicle:
White = Ground - 1
Blue = Electric Brakes - 2
Green = Tail and clearance lights - 3
Black = Battery, aux power - 4
Red = Left turn/Brake - 5
Brown = Right turn Brake - 6
Yellow = Auxilliary or Reverse - 7

In both cases 4 is battery and 7 is reverse, aux or not used.

Double check your wiring using these lists as a reference.

This should get us closer to the answer.

Best regards,
Mike

SOURCE: LEFT TRAILER TURN SIGNAL DOES NOT WORK

I have seen once before that the fuse box was bad on a 2003 Dodge 3500. I had power in and nothing out. We had to replace the box. Not cheap! Hope it is simple like a loose connection though. I think I had to pull the inner fender on the drivers side to access the bottom of the fuse box. Pain in the ****, but...

The left tail light on my trailer doesnt work.the stop and turn signal works . is there a fuse for it? i have 2011 gmc sierra 1500


There is a tail lights fuse for the truck, but not for the trailer.
First, check that your left tail light on the truck is working, if not fix the problem (new bulb, bad contact, fuse).
Then the obvious suggestions regarding the trailer are: Check the tail light portion of the bulb to be sure it is not blown. If good (best to put in new one to be sure), then check the wiring from the front of the trailer all of the way to the non working bulb, including every connection and at any place it is secured to the trailer frame. If all is good with the trailer circuit and bulb, then check the truck's trailer connector, including any adapters. If by chance the truck is wired with a flat 4 wire harness the problem may be solved (but usually the blinkers are the problem). Modern trucks require a 5 wire harness which self adapts to the standard 4 wire trailer circuit. Check for dc power (12 volts) from the truck's female connector. One wire will be ground, others will be taillights (turn on headlights), brake lights (have someone press brake pedal), and blinkers (turn on switch and blinkers).

If the blinker is working on the truck then fuse is good, this sounds like a bad bulb or connection to the light, the brake and signal use the same filement in the bulb. check the bulb first, next thing to determine if its the trailer wiring or the truck socket, use a testlight and test the connector or the wire at the trailer connector and see if there power in the wire, but check close to connector if theres power coming out the connector then it in the trailer wiring or bulb,. also im not sure what this trailer turn relay rh is that you speak off. the only thing i could think of is to converter the signal and brake on the truck to operate the same bulb on the trailer, if this is what you installed then check that wiring also as the controls the lights to the trailer, but if this truck was built with the tow package then it should of be wiring already for this. here a good site to help you with the wiring as this gets hard to explain over the computer, but again test the tow connector on the truck first with a testlight, this way you will be able to see if it the trailer wiring or the truck wiring to connector. google trailerlightwiring. good day. let me know if you have any other questions.

It does sound as though the trailer connection is the source of the problem, check to see if the wiring has been resting on the exhaust pipe and melted through, shorting the wires. Also check if it is squashed or damaged anywhere. Failing this you may have to pull the trailer connector apart and see if the wires have come out inside and are touching, this can happen if the trailer connector is pulled hard.

No left blinker/stop at 7pin connector


its actually located in the TIPM. more like a internal circuit breaker to protect the system. will have to have the TIPM reconfigured to vehicle spec with the dealer scan tool. problem is it doesnt always work because it shorts it out and/or you can only do it a couple of times berfore it has to be replaced

No running lights on camper trailer


Hey Paul, it's most likely a wiring problem. There is one wire designated for just the running lights. What type of plug does the truck have? Probably 6 or 7 way (6 or 7 wire). You can check the plug-in at the truck with a multi-meter to see if there's power at that point. If there is, then the problem is somewhere from the trailer plug to the lights on the trailer. If you have a 7 way plug, the center plug is for aux. power (back up lights on what you pull, if equipped). One wire is power to the camper battery for a breakaway switch, one for left turn and stop, one for right turn and stop, a ground wire, one for running lights, and one for trailer brakes. To determine what wire does what, 1st with meter check volts of all wires w/ truck and trailer hooked up, truck running, power wire to battery for breakaway should show voltage if equipped w/ a trickle charge, brake wire will show low voltage, approx. 2 volts, apply brakes and should go up to approx. 12 volts, put on L turn signal, meter should go up and down, as power to blinker pulses on and off, do the same to determine which is the R turn signal (put foot on truck brakes will show voltage to brake lights AND brakes, continue w/ process of elimination to determine which is running lights, and exactly where power is not going.

Check the plug at the back of the truck for corrosion. The brown wire entering the truck plug should be the the running lights, if no juice at truck plug in, you need to trace it back to the source looking for broken, pinched, wires, or poor connections.

Trailer wiring diagram


Either buy an adapter that will go into your existing harness, usually up under, near rear bumper, you pull connector apart & put adapter in line, then you plug new flat4 into it. Otherwise I would pull inside covers of both tailights, use a 12 VDC light tester, and probe wires at right signal for flashing with blinker,and attach Green wire, from flat4 to it. Do same on left side & attach yellow flat 4 to it. Turn off blinkers, and just put your running lights on, Find wire with power on either side when running lights on, and attach brown flat 4 to it. Now find some clean metal in the area and attach white wire (ground) to it. Put inside covers back on & your done.

2001 Sportage Trailer wire connections


brown to the tail lights. yellow to left turn signal. green to right turn signal. this is a basic 3 wire hook-up i use all the time w/4wire connectors for all trailers. white wire is not used. ground is established when you hook to the ball.
to find the correct wire to splice to, use a testor (has a clip to the bare wire, and a sharp point to the truck frame). using a needle, push it through a wire to rear light harness. turn on the turn signal. check if the connection is the blinker, testing until you have the blinker wire. the tail lights can be attached to the license plate wire. brakes and blinkers use same wire, so brake lights will work whenever the turn signal is attached.
to be sure everything is working right, have a second person go inside the truck and work the signals, brakes and lights one at a time while you are at the back of the trailer telling what to do.
