Brake Lights

Maybe someone can help me with my 1990 YJ Issue...

I replace my brake lights with flush mount LEDs a year ago everything works until last night. When my headlights are off and I press the brake pedal one of my brake lights(passenger) is not working now when I turn on the headlights both work fine turn signal ect. The only thing I did was upgrade my headlight wiring harness which I ordered from Eautoworks.

When you upgraded the harness, you added a new relay and new wiring? New headlights? HID? Halogen? Correct size wire?

Sometimes it's easier to undo what you did to see if you do have tail lights, and you probably do, like you did before you did the upgrade many people do, oftentimes incorrectly, like many did, before doing any modifications like you did.

Could likely be a bad ground on one of the tail lights. Older Dodge Ram pickups had this issue when the left rear taillight ground would get bad contact.

When you wired these led in what wire did you use for ground?

A 89 yj with a 4.0 aw4 sye out of an 92xj. Now the hard part is done time to get it up in the air just a bit. Working on 8.8 with 3.73 and lsd for the rear. and new D30 hp with 3.73 .
For those who have not figured this out I'm old school but can handle the new too.
