The Toyota Tundra Interior Lights Not Working Is Due To A Blown Fuse.
Disconnect your trailer but leave the cable hooked up and see if your lights work; But on my old explorer it was at the top of the brake pedal. #6 · sep 7, 2014.
Checked All The Fuses And They All Seem Good.

You would have to trace the harness under the dash, down the kick panel and under the hood. Toyota tundra 2001 back light dash lights are out (the ones that light the dash) i changed the bulbs, and the fuses are good. At some point the power is not getting from point a to point b.

Checked the harness where the kit plugs in and there's two spots that don't light up, everything else has power. Probably 6 or 7 way (6 or 7 wire). Turn signal and brake light work on truck but the right side turn and brake do not work on trailer i checked fuses inside and in engine they are fine is there anything else i need to check.
If The Signals Are Correct Going Into The Box, You Know That The Truck Is Not The Problem.
Check for voltage at the flasher with the hazard switch on. On the cover of the fuse box you will find a diagram, which will guide you to which fuse is responsible for the interior light. If not the fuse, then it's the brake switch connected to the brake pedal somewhere.
