I have a 1997 Aerostar and would like to wire for trailer lights. I opened the panel on the left side just in front of the tail lights and found a couple wiring receptacles. Are these for trailer wiring? Thanks, Rick

You have to get a trouble light or meter, you are going to have a wire for 1, brakes 2, tail lights, 3 Left turn, 4, right turn.

Find the tail light fuses.
They should be under the hood near the battery by the firewall. If not there look under the dash to the left of the driver.
If it's not a fuse, then it's probably a broken hot or ground wire in the wiring to the trailer.
Hope this helps.

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.

If the brake and turn signal are on the same bulb than you can Orin straight wiring. If the brake and turn signal are on different bulbs than you'll need a wiring harness with a converter box. I'm pretty sure the wrangler has the brake and turn signal on the Same bulb so let's start with basic trailer wiring. The green wire on the trailer harness is for the right side turn and brake for the trailer. This wire should be attached to the wire on the vehicle that supplies power to the right turn signal/ brake light. The yellow wire is the left turn signal, brake light on the trailer and should be attached to the wire on the vehicle that supplies power to the left turn signal /brake light. The brown wire is the tail lights on the trailer and should be attached to either the left or right side wire on the vehicle that supplies power to the tail lights. The white wire is grounD and it is vitally important that this wire be attached to the vehicle in a manor that supplies a good ground. Failure to suppy a good ground will result in all kinds of funky problems with the trailerer lighting such as all the lights linking when the tail lights and turn signals are on at the same time. If you have any specific questions I will be more than happy to try and help. Good luck.

Hi, I'm not clear about what you said. Please tell me the year and model of the truck and what color wires you have on the trailer. A normal 4-wire trailer has brown for tail, green for left and yellow for right. White is ground.

A test light checking each connector would be faster and easier to do. Maybe somebody may have a illustration for you but by far a simple test light is all you need with a helper turning on the different lights as you check them out and writing all your findings down

4 way flat molded connectors allow basic hookup for three lighting functions; right turn signal / stop light (green), left turn signal / stop light (yellow), taillight / license / side marker (brown) and a ground (white).brownwire will run both right and left side markers

Hi There,

There are so many plug /trailer type combos that I finally made a list and posted them as a tip.

Check the wires at the connection point and follow them back up to the tail light look for any disconnected wires or grounds. Good luck.

I found out it had a after market trailer hitch lighting, and it had its own little circut board, and the board was all burnt up. So all I did was cut the wires and took the wiring harness out and works like new...
