I installed a trailer brake controller in my XJ and I purchased a kit for wiring the the 7-wire plug. The kit came with the wiring, plug, breakers, etc. The instructions say the 12v hot lead from the + batt cable to the rear should run through a 40 amp breaker. However, this is 10 gauge wire I'm using, which is rated for 30 amps max. Aren't these instructions wrong? Shouldn't I be running this through a 30 amp breaker?
Thanks for any help.
