What is this thing?

I can't find any info on this thing I have no idea what it does. I am talking about the black button console not the tpms set button. Thanks everyone

 

Looks like an aftermarket alarm light.

 

What does it do when you push it?

 

Nothing the "button" you can see doesn't push but there is a spring loaded button on the back

 

Then I agree with Elblancotaco... Aftermarket alarm light


Although, I'm curious, what does the spring button on the back do?

 

I have a similar button on mine.
If I read correctly, it is for a trailer with electric brakes. You press that button to allow power to be sent to the brakes when you're hooked up.
I read that a while back in the owners manual for trucks with the tow package setup.
Could be wrong though.

 

Trans brake or Nitrous ?????

 

Dumb dealer installed alarm that literally does nothing because you didn't pay the $200+ fee to have it turned on when you bought the vehicle... I've got the same BS and my entire wiring harness and fuse box is a rats nest because all they did was use taps to install it and electrical tape which hasn't held up.

That's exactly how I felt about the Karr system which came with my pre-owned truck. It took me two hours to carefully remove it and recrimp the starter wire. I left the taps on after removing one and seeing how it destroyed the wire insulation.

OP follow where those wires go. If it's to a box with three to five harnesses it's likely an alarm system.

 

Eject button? j/k

Is there a brand name on it anywhere?

 

Aftermarket garbage. Asked the same question when I got my truck

This is basically what a brake controller looks like:

 

Correction
Page 236 of the manual "service connector for towing brake controller (vehicles with 7 pin connector)"
Very well could be something else, only way to know would be to follow the wires like @road2cycle stated

 

Oh that?? That's a mark I dickfer, different from a henweigh. No, it valet button for aftermarket alarm

 

Hold the button to bypass alarm.if wired correctly.

 

That thing is huge... And what a spot, no the car thief will never find it..geez
