So if I change the gauge of the main power supply wire to the harness I might be able to use it with the PIAA’s?

Power wire supplying power to the 30 terminals should be 10ga or 8ga so no voltage drop. You can use one relay to turn power on for the low beam lights. Two relays can switch from lo to hi or just to turn the hi beams on.
