Correct, but it doesn't ground at the dash cluster, it grounds at the brake pedal.

Are you saying I need to run the ground to the pedal?

There is already a wire that runs from the dash to the pedal. He's just saying the dash is grounded at the pedal and the body where they meet.

By pedal you are talking emergency brake pedal.

Yes, the ground side of the dash light goes to the wire on top of the emergency brake light switch. It also goes to the purportioning valve to indicate a failed brake hyd circuit. When either switch closes, it completes circuit to ground.

Did you test the bulb before install? You should be able to use a jumper (to ground) to light it to test the socket and power to bulb.

If nogo with the jumper, break out the test light or multi-meter and see why no power.

Hey ummm on the same subject. Mine brake light won't go off. Don't want to hi-jack your thread but figured since you guys were kinda already on the subject I'd ask.

Alright thanks. I'll take a closer look tomorrow. When I got home later today, I couldn't test the voltage cause my battery was dead. I accidentally left one of the doors open, after doing some wiring work last night, and the interior lights were inadvertently left on. I can't remember if there was ever a buzzer/ alarm that would go off when doors were left open. Does anyone know? I have a '89 YJ. If not, can I rig one up?

Tomorrow I have the morning off, so I'll recharge my battery and take a closer look at the wiring. I think I got my wires crossed somewhere. No pun intended.

Thanks for all your help!

Funny! Earlier today when I did a google search on my problem I found this:

http://www.wranglerforum.com/f8/brak...on-144026.html

Not sure this will help you but at least it's a start. My google search was "YJ Jeep brake dash light not working". Hope you figure it out. Good luck!

I have found the door activated lights rather usless and prone to do what happened to you. I disconnect my switches as I often have the doors open or off completely.

Yeah you can rig a buzzer. It needs power and you complete the ground with the door switches.

Yeah, I get what your saying. I'm thinking about doing the same but then again, I do like the idea of a light down there. Maybe it would be a good idea to rig some better lighting down and tie in a buzzer.
