On my 1999 chevy caviler both my brake light and blinkers dont work besides the problem being the "pigs tail" what else could it be?

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.

I would check your tail light fuse first then test the brown wire in the tail light harness where you origionally cut into it. With the lights on there should be around 12v on it. if not you may have pulled the wire too hard and broke it upstream. Test to see if there is 12v at the fuse ad if there is, your trouble should be in the wire between the fuse and the spot where you cut into it.

the fuse is out or blown check the fuse box

Sounds to be in your pig tail. Might take some electronic spry cleaner , WD/40 work sometimes. Should just be in the connection. good luck

I've worked on these the first drove me crazy. its the turn signal switch every thing runs thru these. head lights, turn signal, brakes. except the third brake light. it runs directly from the brake switch. go figuare

The kits are great, they work, They eliminate the need for running extra wires for the brake and blinker, they don't mix well. Also, you need a real good ground on your trailer or you will get dim lights, or no lights at all.

ck the rear tail light pig tail,,to see if its got power,,test light,,broken wirer or parking light ground

The Blinkers and the Brake Lights are the same bulb. So check the brake light switch. Flashers use a different flasher unit, than the turn signals

try running your own earth wire to your pigs tail---WOW AMERICAN ,iam getting their

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.
