It is real simple, really! Since you want to rewire it from the front, find the blue wire in you trailer plug, this is the hot wire for the brakes. Look for the white wire, this is the ground for the whole coach. Run 2 wires to the front wheel on both sides, I used 10 gauge, one blue and one white. Then I used 12 gauge wire from the front wheel to the rear wheel on each side. There is 2 wires that come out of the backing plate for the brakes, it does not matter which one is hooked to the blue or white wire. I used soldered connectors that I crimped then soldered and insulated with heat shrink. The theory of running equal lengths of wire to each wheel is, all wheels receive the same voltage and amp capacity to all work equally. Don't forget to wire your break away switch in between the battery positive and the blue wire.
