Common Issues
Before diving into the wiring diagram, let’s discuss some common issues you may be experiencing with your tail lights. The most common issue is that the tail lights may not be turning on.

If any of these issues sound familiar, it’s time to take a closer look at your wiring diagram.
Blown Fuse
One common issue that can cause the tail lights to not turn on is a blown fuse. The fuse is located in the fuse box under the dash on the driver’s side. The fuse box cover should have a diagram that shows which fuse is for the tail lights. If the fuse is blown, replace it with a new one of the same amperage.
Faulty Switch
Another common issue that can cause the tail lights to not turn on is a faulty switch. The switch is located on the dash to the left of the steering wheel. If the switch is faulty, it will need to be replaced. You can test the switch with a multimeter to see if it’s working properly.
Bad Connection
If your tail lights are not as bright as they should be, it could be due to a bad connection. Make sure the connections are clean and free of corrosion. You can also check the ground connection to make sure it’s secure.
