Trailer brake wiring

What gauge wire and color is used in my rig from the factory to wire the trailer brakes? (7K axles) Where are the grounds wires for the magnets mounted? Thanks for your help-I am going to rewire my brakes to heavier wire. Also are they using a 20Amp or 30Amp fuse? Steve

Brake wire color is blue and probably 12 -14 gage. all grounds should be to the frame and battery and TV.Not sure what fuse they are using I think I have a 20 on my disc brakes.

I looked at it. Thanks for the info- blue 12 gauge wire. with small 18 gauge jumpers to drum brake connections. I think I am going to use their 12 gauge to the drums first and check amps. If too low I will run 10 gauge.
