Here’s how I wired mine. I used two 60 amp Bosch style relays and located them on the firewall above the hi/low beam switch. I used a 40 amp fused single 10 gauge wire to supply both relays. It works great.

I picked up the 12v supply from the starter lug but you can use the alternator. Either place works, whatever is easier.
