Here is an updated link with information for anyone wishing to install electric
brakes on their trailer and a brake controller in their vehicle.
Trailer is a 1976
Boler with a 3500 lb rubber torsion
axle.
My tow vehicle is a 2002 GMC Sonoma which required that I splice into my stoplight switch as well as drill an access hole through my firewall to route my wiring.
Some vehicles which have been pre-wired for a 7-way trailer connection will have a "plug-n-play" wiring harness that will not require the above two steps. (even easier)
I will also be adding to the photo set when I install my breakaway switch and when I demonstrate the use of the brake controller.
If anyone spots any errors or omissions please let me know.
