Question about 1995 Jeep Grand Cherokee

1 Answer

Trailer running lights

I run an aftermarket harness to provide trailer lighting. I can only run a couple of 1157/1158 bulbs for running lights. Any more than that and the signal box (the controller at the rear of the vehicle) on the jeep overloads. I loose running lights on both the jeep and the trailer. The turn signals, brakes lights and flashers are not affected. After shutdown and a few minutes wait, the running lights will work again.

    That's an interesting question...Perhaps jeep offers a different H/D controller with their trailer package??? Also, check with a U haul if there's one nearby.
    I really want to know how this one turns out!!!

Try http://www.etrailer.com/faq-wiring.aspx. They have very good concise information that might help. It sounds like the converter is getting hot and losing connection. Check all grounds.

92 chevy Silverado 1500 blinkers do not work


Is it wired for a trailer light harness? If "yes", is the wiring OEM or aftermarket? You may have a short in the truck's trailer wiring harness, or you may have a problem with the multi-function turn signal lever/wiring, the flasher(s) located under the dash may be defective, or you may simply have burned-out turn signal bulbs (if a front or rear bulb on either side is blown, the signal on that side may not operate). Start the truck, operate the turn signal lever and visually check to see if it's blinking

Wiring diagram


Hook up the trailer to the vehicle. Under the rear bumper you will find a thick wire harness that runs from left to right or vica versa. Choose a location to strip open the harness to gain access to the different color wires. Open the trailer coupling. remove all wires and split them apart. Now start with say the right indicator light on the vehicle. Earth should be established via the grounding method of the trailer hook steel on steel of the vehicle. Connect any wire of the trailer to the now flashing right indicator light. Go through them all till the right indicator bulb flashes on the trailer. A good approach to determine which wire is active, is to make a test light from an old bulb connector some have already two wires connected ie; pos neg. neg the tester onto any part of the vehicle chassis and the pos to the now live wire. Go through them all till all wires meet up. Now go on and extend the harness by means of soldering properly and insulating that wire from the main harness to the female fitting of the trailer connector. At each connection on the fitting fit on properly the different wires and do the same to the male connector from the trailer so that all lines up inside the two connectors. Good luck

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

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.

The running lights on my boat trailer are not functioning. I am not getting the voltage for the running lights circuit from the harness attached to my 2001 Durango I have checked the harness and...


You might be dealing with a grounding problem- better stated, a lack of grounding problem. If your trailer wiring doesn't have a dedicated ground wire, the trailer relies on the hitch continuity to complete a grounding circuit to the towing vehicle. You can test this idea a couple of different ways:
1. Unhook the trailer from the Durango, remove your hitch / ball and wire brush the daylights out of it. It may be corroded badly enough that it keeps your trailer from grounding back to the Durango.
2. When you're hooked up to the trailer and the lights are on, use a piece of wire to touch bare metal on both the trailer and the Durango at the same time. This will provide a grounding path and show whether or not this is a problem.

If this isn't the problem, your vehicle may have a fuse that protects the trailer light circuit. Check your manual for information.

Good luck to you.

Trailer hitch...no running lights (2004)


You'll have to follow the BROWN wire from the factory connector(with the running lights on of course) to the trailer connector and make sure you are getting power all the way to the two lamp fixtures. If so you've probably got two burned out 1157 bulbs or an inline fuse in the factory harness/ trailer harness.Good Luck, Dana
