Third brake light wiring diagram

Need a wiring diagram or routing for the third brake light

Posted by on

  • Mark Emerson May 08, 2013

    I found that there are 2 green and black wires for the brake lights and the third brake light. One of them go to the lamp failure sensor , which was my problem,( it was corroded inside the box itself,) the other goes from the fwd fuse box directly to the rear brake lights, confusing when nothing said anything about 2 different black and green wires going separate ways. The sensor is in the trunk on the left sidewall.

Testimonial: "Thank you, but it doesnt locate anything on the vehicle itself. I just took the back seat and back out and traced the wiring myself and I found that the light failure sensor is at fault. At around 300$ I think I will find a way to bypass it. Thank You again !"

Third eye works no rear signal or brake lights


The high mount brake light gets its own signal from the brake light switch (on the brake pedal). Or at least the wire leaving the brake light switch will splice, one wire to the high mount brake light, and the other for the rear brake lights is routed through the turn signal switch, and coordinated there with the turn signal wires to the rear brake lights. The brake wires and turn signal wires share the same wire, and same filament in the bulbs. It is kind of complicated, but brakes applied with no turn signal, brake light wire goes from brake light switch through the turn switch and out to the bulbs. If brakes applied with turning signal, non blinking brake light wire goes from turn switch to rear light, while the turning signal wire will go through the flasher relay, and then to the rear light to cause blinking.

I hope that makes sense. It appears the problem may be in the turn signal switch for both the turn signals and the rear brake lights.

HOW TO WIRE BRAKE LIGHTS FROM THIRD LIGHT 97 MONTE CARLO


Instead of improvising, why not get the stop lamps working the way they should be. You must be getting power through 15A fuse 23 in the fuse block and the stop lamp switch, otherwise the high mounted stop lamps would not work. Stop lamp power is routed through the turn signal switch and is applied to the tail/turn/stop-lamps. That should solve your problem

How do I replace Brake light switch?


Make sure the switch is the culprit. Do the other taillights work when braking? if so, look for a problem elsewhere, such as wiring to the 3rd light. Give special attention where the cable is routed through the trunk lid.

Third brake light flashing when engine is off, no main brake lights


this does not sound like a fuse problem. seems like a wiring issue. You probably have wires shorted together, and/or shorts to ground somewhere.

Brake switch is a good place to start, make sure it's working fine. To find the wiring issue you will need electrical diagrams, so get yourself a repair manual for a 1998 Explorer.

Look at connectors, see if you can find components or connections where all the brake light and tail lights connect to together. Using a multi meter you should be able to pin point the issue if u follow the wiring from the battery to the lights using the diagrams and checking connectors.

2005 Lincoln Ls 3rd Brake Light Wiring


The best way to wire a third brake light is to run the wire directly from the brake light switch on the side of the steering colum to the light. You will need a test light to find out what wire lights up when you push the brake pedal. Then you can splice into it when you run your wire to the rear light.
