How I disabled the annoying little back up alarm.
 

Towing a trailer without brakes? Long loads with tailgate down? Tired of the beep beep beep every time you put it in reverse? Tired of disabling it every time you started the truck. I was!!!

Link did not work but Google Tekonsha 6562-A Emulator. Fools the computer to sense the magnets of trailer brakes!!! Just plug it in like you would a trailer!!!!
