Wiring questions

I just installed led tail lights on 89 YJ. Tail lights work. No turn signal, brake lights or back up lights. Tail lights go out when brakes are pressed. Any suggestions?

 

What lights did you use?

 

Partsam 38. Complete light.

 

That may be the problem....

"These rear combination tail lights have studs on back sticking out will bolt to any flat surface; This is not a replacement for Wrangler YJ CJ JK tail lights, not factory mount. If you want to install it on wrangler trucks, you may need some modification: There is no wiring harness so you have to splice the wires yourself. Also, The bolt holes are larger than stock so you will need to drill out your body to make them fit. The entire assembly is a touch larger than stock as well"

 

Using the wiring diagram on the taillights Amazon ad and the taillight wiring diagram for an 87 Wrangler here is what I came up with for you to confirm that the taillight is wired correctly. It definitely sounds like it's a ground issue.

 

Thank you. I was expecting a grounding issue. An was wondering about running more wires to back as mine now uses same wire wire for tail light, marker and brakes.

 

Sorry, here is a wiring diagram for a 90 Wrangler, wire colors are the same.

 

Blue wire should be taillight, Gray/Black (left) and Brown (right) should be brake and turn.
Check you ground wire connection to the body.
