Adding a Third Brake Light to M1009

[tgtaylor64]

I just bought a low-profile LED third brake light and want to mount it on top of my M1009. It has two wires: black and yellow. How do I connect this to my truck? I already have a 4-pin trailer towing cable hooked in and thought it may be easier to just connect to that. I thought it would be really easy but I cannot keep the new light from blinking when the turn signal is on! What am I missing?

The brake lights and blinkers are powered on the same wire going to the rear of the truck . To power a 3rd light you need to run a wire from the brake light switch ( on the brake pedal assembly) and a wire to ground.

Cool thing is the third brake light will flash when you have the 4 ways on. That is when you hook it up to the brake pedal switch. Works well with out any issues.

or a inline isolator box like newer vehicles require to separate them . can be had fairly cheep and keeps the system separate from vehicle also .

Just hooked it up as directed (ran the yellow wire to the white/black wire on the brake pedal switch) and it works perfectly.

Could you post some pics of how it looks?

That light looks really good!


But that high gloss desert tan is just.... wrong.....

A little bling action on the 1009s is kinda neat,especially with a really nice body.When I redo my 86 the body will be super straight and painted in a matte gloss paint.It will be camo though.I grew up in a body shop and if it wasn't straight it didn't get paint.Nice job on that third brake light,but I would like to recess mine into the tailgate.

I'd like a 3rd light because my dirt bike on the back blocks a decent amount of the regular lights. I think I'd like mine recessed into the Fiberglass top or just at the top of the window.
