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.

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.

Relay and module


I think you might be talking about the "Trailer Lighting Converter" or the "Tow Ready" Tail Light Converter, or they may call it a trailer light module. This module plugs into the vehicles OEM harness. If this failed then you could have such symptoms. But they could also be talking about the "Trailer Light Socket" (your trailer electrical plug plugs into this socket). I hope this helps. If not try to give more details. Good luck.

Only left trailer blinker and brake light work when I hook up my trailer. Just got this 2006 Nissan Titan and everything worked on my trailer before. There was no TRAILER TURN RH relay installed in the...


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.

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.

Trailer brakes


Take a 12 volt test light... the kind that has a spring loaded clip to hold the probe into the wire, and insert it into the wire just before the trailer plug, vehicle side. (Blue I think) If there is a connection, the brake should see it and you should have an indicator light. When you activate the brake the test light should lite up. If not, move up to the brake actuator and test the blue wire. If there is nothing at the actuator, check the black wire. It is power to the controller. If no power there, check fuses again. If it does pick it up at the plug, connect the trailer and test the trailer itself. First ground to the trailer and then to the truck. Most problems are ground wire related. Then move to the axle and test it there. For the brakes to work, and even show on the indicator, there has to be a ground and power to the brakes themselves. There are 2 wires to each brake... a ground and a power. Test across both wires to make sure you have power and ground. You can also hook another trailer to your truck or another truck to your trailer. Lights can work through trailer ball ground. Brakes can't. leave the trailer unhooked from the trailer and hook the wiring up and test the lights. That usually will indicate a good or faulty ground. Also make sure there is a GOOD ground to the truck frame/body. Also try http://www.etrailer.com/faq-wiring.aspx. They have a great website with lots of info. Hope this helps. Mike

Need wirering diagram to hook up trailer lights and elecric break


Also try http://www.etrailer.com/faq-wiring.aspx. They have a great website with lots of info. With the tow package, there should be a plug under the dash... far left above the emerg. brake petal. The harness that plugs into it should have came with the truck, or you can order one to fit it. Did thew truck come with a 7 pin plug on the back? If not you can order one from the above mentioned site. They also have the wiring colors.

Tow plug


you have one of two things going on first check to see if the brake light on the left side is shorted out, it will be a 1157 bulb replace it and see if it works looking good does not mean it's good if it has a single contact then it's a 1156 bulb, check to make sure where the bulb socket is that the rubber inside the socket is not worn out and the bulb is shorting to ground. if it is buy a 1157 pig tail repair kit at any Nappa auto truck store or any trailer store. replace it if it needs it. Next if that does not fix it pull the left wheel off pull the drum off and look at the wires on the inside, if they are bare inside it's shorting out if you don't see a bare wire look at the color of the two wires and with a ohm meter and one wire disconnected from that side touch them at the plug and to ground one at a time you should have one wire going to ground one not if both wires going to the left side show they are shorted then you need to replace the wire or the electric coil. if you need more help just ask. If I can e-mail you I can send you a diagram and show you how to test if yo don't know. good luck.

I have power to my trailer recept but nothing after that


Sounds to me to be a groung issue. Have you tried to hook an external ground between the truck and trailer? If you got everything at the plug thats not the problem.

Pressing brake causing blinker issue


The trailer harness that was installed probably has a short inside the box that distributes power to the trailer pig-tail. Remove the trailer harness. You problem will be cured.
