i just used one side to power two relays... one for the highs, one for the lows.... the driver side lowbeam power wire turns on the relay that powers both lowbeams.... the driver side highbeam power wire turns on the relay that powers both highbeams... all grounds are wired back to a heavy common. I used two $4 relays from autozone... it does NOT have an 87a, but has two 87's... so i could use one for each side, so each of the total 4 headlight filiments has its own source terminal. I used a fused 10 gauge wire to provide batter power... then from the relays, i used 12 ga 4 wire trailer wiring to run to the lights, wired to new H4 harnesses.. i used the white, yellow, and brown of the trailer wiring, and pulled the green off to make a 3 wired strand.
