Helpful Expert Reply:

If you installed the Autowbrake Electric Brake Controller # 3430001 on a trailer it would not allow the vehicle's brake controller to activate the brakes since that circuit would not run to the tow vehicle at all anymore and would only run to the # 3430001.

What if I want to use my trailer with the brake controller in the tow vehicle? Do I have to uninstall the Autowbrake or is there a way to switch back and forth? 69887

If you wanted to use the brake controller from your tow vehicle, the Autowbrake would need to be completely removed. This is because the blue brake output wire from the tow vehicle's 7-Way (which is what your controller uses to send power to the trailer brakes) isn't wired to the Autowbrake at all. 56844
