I checked the bulbs and everything. The brake lights work fine, the reverse lights work but my tail and plait lights don’t. The bulb for the tail and brake lights are the same.

Welcome to 2CarPros.

There are two areas that come to mind when these lights don't work. First, the power supply to them is spliced together in the trunk area. Also, they all have a common ground.

I attached a pic from the wiring schematic showing the splice and describing its location. I need you to check its condition. Make sure it isn't damaged, corroded, broken and so on. If it looks good, confirm there is power at the splice.

I also circled the ground for them. However, I really don't feel that is the problem since the other lights are working.

Here are a few links you may find helpful:

Let me know what you find or if you have other questions.

Take care,
Joe
