Trailer Brake Controller Wiring For 2003 Sonoma

[kevincalgary]

Is there a wiring harness available for a 2003 Sonoma that will allow me to simply plug into the existing wiring to complete the connection for my trailer brakes?

 

I know it is available for the larger trucks however my research so far leads me to believe I will have to manually tap into my existing wiring to my brake pedal and run a lead to my battery.

 

Thank you

The plug in connection is only on the full size. I had to tap into the brake switch and get power off the bat. for my 07 Canyon.
