So I have probably re wired the rear of my Jeep 20 flipping times not really but I feel like it....anyways I have these trailer lights on my Jeep two wires do these trailer lights ground themselves???? I have a new harness from ex wiring I have blinker lights going to one wire and tail lights going to the other...one prong light up on the light but still no brake lights when pedal is pushed.

I don't have a new.blinker arm yet so none of them wires are hooked up don't know if that has anything to do with the brakes or not.


Thanks you guys
 
Check and make sure the brake light switch is getting power out. Easy enough to wedge something in there to hold it down while you check with a volt meter or test light. There are only a few wires going back there.:chug:

You mean the little plunger switch on the brake pedal? I have to wires that I am assuming hook up to the front of it they are labeled brake switch and brake switch power one is orange the other white

Without those two wires attached to the switch, you will never have brake lights.
 
I have them connected but I don't have a blinker arm yet would that have.anything to do with it?

I don't think so. That arm shouldn't have anything to do with it. I would get it all hooked up the way you think it goes and then try trouble shooting. There might be a missing link that makes it all work. Make sure it is all hooked up.

Just go back over it all and make sure.

What is a third brake? I don't have it hooked to anything.
 
That is a third brake light. The one in the middle on newer vehicles. Unless you have added one, it just ain't there on a CJ:D

How does that switch on the brake pedal get power? Cause I have no wires hooked to it pausing the brake pedal down and touch it with test light I get nothing....but I do have a wire that sais brake switch power which is the orange one and it does have juice but my white wire has no power.

I'm so lost
 
The switch gets its power from the orange wire. The white wire is what completes the circuit and sends power to the brake light bulbs, illuminating them.

If you can activate the switch, (I don't know if it is a normally open or normally closed switch, check by seeing how the brake pedal activates it), you should have power to the white wire and thus your brake lights.

Please don't take my response as being a smart :censored:, I personally have a very bad habit of over analyzing things:D.

Easiest thing to do might be to remove the switch from the pedal assembly so you can easily manipulate it and see if it works correctly with the wires attached. They might just be connected backward if it even matters on this part.:chug:
 
You should have a hot wire to the switch and a wire to the tail lights and when you push the brake pedal it pushes on the button on the switch and that complets the circuit sending power to the tail lights.

No offense taken lol...so let me explain what all I have here because nothing seems to be working for me and from what I here this is suppose to be simple so here we go.

I have two trailer lights with a red and brown wire I have two side marker lights with a white and black wire.

I have a wire that goes to the tail for tail lights left and right tail lights, I have 2 more wires that go to the tail for left and right blinkers.

I have a little switch on my brake pedal with two spots for a connection on one of them connection spots I have an orange wire labeled brake switch power it goes from switch to um... fuse and yes it has power going through it the other spot I have a white wire connected labeled brake switch that wire goes directly to my blinker arm which I do not currently have right now.

So what do I need to do?
 
Make sure you are getting power from the fuse box, ( check the fuses to make sure they are good and making contact at both ends) if so then push the pedal. You should have power coming out of the switch, if you have power coming in. If not Bad switch.

I've already don't all that. Not sure how the switch goes bad if its powered by the fuse block I'm almost certain it has something to do with the blinker switch.
