I had the dealer install the factory trailer hitch and wiring. I've towed using the flat 4 plug with no problems. I recently towed using the Bargman 7 pin. Anytime I touch the brake pedal it locks up the trailer brakes. I've found the electronic module. No adjustment or instructions.
Is there any way to adjust the trailer brake sensitivity?
