I’ve recently installed the opt7 redline triple on my truck. I followed some of the other posts on here to correctly hard wire into my tail lights. Everything is working except for my brake lights. I understand on my light bar that the turn signal and brake light share a wire but it seems as in my tail light they do not so if anyone has a suggestion please help just trying to get this to work correctly. Thanks in advance.

 

Do you have incandescent or led taillights taillights?

 

Edit:I don’t think they’re leds. I do believe it is incandescent. After some research

 

The only time the bottom row (running, brake) brightens is when I unlock my truck or when I first turn it on.

 

So here is the taillight wiring diagrams and the connector views for both taillights.
The light bar uses a flat four trailer connector, one is ground, one is running lights, one if left turn/brake, one if right turn/brake.
I would check that you spliced the correct wires to each other along with making sure all the spliced are well done.

 

so as the pictures show, when I splice into wire #1 for stop/turn (right or left) the blinkers don’t work and when I splice into #3 for turn lamp (right or left) rear then the brake lights don’t work.

 

If I use wire #1 the brake lights work but not the blinkers. If I use wire #3 the blinkers work but not the tail lights. What’s the solution here?
