The piece that you may be missing is GROUND. You must have a wired ground. You cannot rely on the hitch to carry a circuit. Grounding though the frame deteriorates over time. Sometimes you have to run a ground wire to the tail lights.

Check the plug wiring again on the truck. You have a wire crossed , when you hit the lights and it only blows with the trailer, then there is a crossed wire on the truck. What seems to be happening is your sending power to the ground for the trailer. You can check the trailers ground with an ohm meter, then make sure your truck ground matches that pin. You may know this , but green rght turn, yellow is left turn, brown is parking lights, black is brake lights, and white is ground.

Right trailer turn signal does not work when hooked up to my 2003 gmc sierra. The light does work on the truck. Trailer light does work when hooked up with my other vehicles.


Check the plug at your gmc outlet, your right signal wire has been damaged before the plug somewhere. If you have a test light switch your right signal on and make sure it is working at the plug on your gmc, you will find it is not working, than trace the wire back from the plug till you find where it has been damaged or you can run a wire straight from plug to your right signal.

04 toyota corrolla I need to wire a harness for a utility trailer, not sure how many wires are needed and do I need 1 or 2 lights on each side of trailer. not sure on these newer cars with more than 4...


First and foremost, installing the wiring harness is not the easiest task, but not the most difficult. Typically you will use a 4 pole harness. One wire goes to tail light on, second wire goes to brake light, then one to left signal and right signal. You will need a test light of some sort in order to determine the hot or live wire for each bulb. Once you confirm the wire you can simply splice the wire off the harness into the factory harness. One thing I will mention at this point is using a typical four pin instead of a adapter that are a it more expensive can cause more draw on your cars electrical system. Although I have never had any problems on my cars. I have heard situations in which wires have become cooked.

As far as trailer lights go it may depend on the state. Here in IL, you can get away with running 1 light on each side of the trailer granted all functions work-brake, running lights and turn signals.

Good luck

it sounds like either the wires controling the left brake light and turn signal are borken or loose on your truck. or there could be a problem with the ground for the trailer hookup. you should take a volt meter and then have someone put the brake on and test at the hook on the truck side to see if you are getting any voltage there and do the same thing with the turn signal. if you do not have any voltage there you need to trace the wires back up into the truck to find where you do have voltage . you may find a broken wire as you go. How many wires are there in your trailer hook up?

Trailer Wiring Harness


for your trailer you need park light, brake light, left and right signal light. the best way is to tap them in the rear tail light wires.

Trailer break lights and running lights don't work


i would use a multimeter to read each wires operation voltage before hooking up. ex. turn on turn signal, connect meter to find which wires is pulsing.

So your saying you wired the trailer yourself? yes you need the wires to both sides for brake and running. the runners have to be all connected, and the brake all connected, hot and neutral.

Tow plug


I take it the blinkers and brake lights work ok when not hooked up to the trailer? If yes, then the wiring to the tow hitch is not hooked up correctly. How many wires to trailer pig tail connection? U can have up to 7 depending on what you tow. Check to make sure these wires are hooked up from the truck to tow plug correctly: 7 wired---
brown-Rt turn and brake light, yellow-backup, white-ground, blue-electric brake, green-tail running lights, black-battery charger, red-left turn signal and brake light. Let me know if u have something other than 7 wire, I'll get the wiring color and source info for u.

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.

Turn signals blink on the wrong side


Your signals don't go through any computer (that is next year, HA,HA), either a connector is hooked up wrong (crossed) to the lights or the wires were worked on and not put back together correctly.
