Tail Lights Don't Work

I have a 1998 Toyota 4Runner. Recently, I installed a trailer wiring harness and now my tail lights and front marking lights won't work. Everything else seems to be fine. I checked the fuse box and didn't see any obvious issues. I sense removed the trailer wiring harness and still no luck.

I would take out the tail light fuse and repace with a known good fuse. Use a test light to see if you are getting power at each side of the fuse at the little metal tabs on the top of the fuse.

If you have power at each location, then something happned at the connection. You may need an owners manual with a wiring diagram.

I dont know how to wire lights to trailer from 1986 toyota pickup


You need a "test light". Then you turn on the circuit you want to wire in, tail lights, brake lights, blinkers and poke around the back of your light sockets until the test light comes on. Then you splicew into that wire and run it to your plug in. If you don't know which wire is what on the trailer, hook it up and with the wire fastened into the truck harness, try it on the trailer harness wires until you get the proper lights working. Process of elimination. Hope this helps.

Tail light running lights, and liscense plate lights dont work, but breaklights, signal, and hazard lights work


The tail lights and licence lamp is all the same circuit, should be a brown wire to all 3, it sounds like its broken in the harness somewhere (especially if the front park lamps work, then the fuse and switch are good). Trace back from rear lights until you find power. Check for pinched wires or cut, or bulges in the wire indicating resistence. Also if you have wired in a trailer plug, disconnect it and retry. Trailer wires are very seldomly wired properly and cause lots of light issues.

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.
