So I'm getting to the end of my build, little things take forever! I have never had a trailer with brakes before and I'm testing all my electric again.
My ? is, dexter axle, electric brakes, one wire to trailer frame, one wire to blue on 7 pin, correct?
Next ? is, if I'm testing the wiring NOT w trailer hooked to vehicle and using battery at the 7 pin, will the brakes not engage just by putting 12 volts on blue wire cuz trailer frame has no ground cuz not hooked to vehicle tow hitch? Make sense? Any help would be appreciated!
