Wiring issues after head unit install - Toyota 4Runner Forum

Alright so installed a new head unit, but here are my issues.

When I have the lights on at night, my dash gauge light and rear tails lights do not turn on. The dash needle are on and can be adjusted by the dimmer. The brakes lights also works.

Fuse for the dash is not blown .

Any thoughts ?

You may want to check if you clipped any wires when cramming the new headunit back in the dash. I had a similar issue in my 911 when I was carelessly pushing things back into the dash. I accidently pinched and severed some wires.

Do you have a back up camera that’s into your tail light?

Is all the tail lights? Both sides, turn signals and brake lights?

The brake lake and turn signal in the rear works. The back up camera wiring hasn’t changed from the previously installed head unit .

I’m about to rip this think apart again. … so depressing
