Anfonyhunt Posted January 19, 2020 Posted January 19, 2020 I am new to the her community and decided to start my first project, a ‘90 MJ. I have spent numerous hours trying to figure out why the driver side taillights are working but the passenger side isn’t. The previous owner butchered up the whole rear lighting harness. So I grabbed one off of another MJ and spliced them together hoping it would fix the issue. It did not change anything. I checked fuses and they are fine. Checked my ground wire on the rear driver side and it’s okay. Any other ideas to look into? Any information helps.

I cleaned up the light sockets. Still no power. I ran a test light on the fuse box and I am getting power to a few but not all.

Ωhm Posted January 20, 2020 Posted January 20, 2020 When tail lamps are ON, one wire (DR BLUE) feeds B+ to all bulbs. Check for B+ everywhere along this wire.
