Dash Lights Out after Brake Controller Intall

Installed a trailer brake controller on my 99 3.4 manual TRD 4x4. Everything seems to work except my dash lights and stereo display. All other lights work. Blue brights indicator works but the normal "headlights on" light does not. Blinker indicators also work. No fuses blown. WTF?

 

I mean why would that stuff have anything to do with anything i did?

 

dimmer get turned all the way down?

 

Check taillight fuse if it's not the dimmer.

 

dimmer is cranked up and all fuses are good. tail lights work fine. Actually, last time I started it the dash lights and stereo display were back. But the "headlights on" indicator is still gone. Something is messed up.

 

Loose wire under dash? Knocked it loose when you put the break controller?

 

Yep. Pretty much. I must have knocked a wire loose or created a short somehow. And it's so hard to wedge my head under there and see anything

 

reach your hand up under there and start wiggling shit
