Super nice condition Tekonsha trailer brake controller.  It is a genuine Tekonsha P3, made in Mexico.  It will fit many trucks, just need to swap out the harness for a different one.  I have one of these on my 2002 Suburban and it's awesome!  I plugged this one in, and it powers up and works normally.  Diagnostics report voltage output when you press the brakes, and when you move the manual lever.  Looks great, even still has the plastic film covering the screen that you can pull off if you want.

The harness included is for Ram 1500/2500/3500/4500/5500 trucks, 2014-2024 basically.  But you can get whatever harness you need pretty cheap, or you can cut this one up and make your own if you don't want to spend the $20 on a harness.

I printed out a copy of the instruction manual also which is included.  These are awesome, and definitely a premium solid-state brake controller.
