So I was driving my 2002 tacoma TRD to work and my trailer wiring harness came lose and was grated down to bare wires. I now have no dash or tail lights. I replaced the wiring harness, converter box, checked the fuse's (all fine) and inspected the bulbs but still no dash or tail lights. Brake, headlights, back up and turn signals all work fine. What am I missing?

 

I would look at your fuse again Is it loose where it pushes into the fuse block??

If that is not the issue check if you have voltage coming into the fuse block with the switch on.

Maybe you lost the ground to that circuit.

 

Thanks for the help. I followed the ground and it was broken. Fixed the break and everything works.
