Yes, I just snipped the headlight wires at the driver side headlight. These wires will control your relays for switching Hi and Low beam.
White wire = Hi beam
Green wire = Lo beam
Black wire = Ground (this wire will no longer be used)
White wire to pin 85 on one relay
Green wire to pin 85 on other relay
ground pin 86 on both relays with same gauge wire
Run 12 gauge wire from batt to pin 30 on both relays. I ran two seperate 12 gauge leads with inline fuses but you could use one lead and splice in a Y just before the relays to feed both relays (you will never use both Hi and Lo at the same time so it won't matter). The only advantage to running two seperate leads is if I lose continuity on one circuit I will still have either hi beam or lo beam to get me home.
Pins 87 will run to the headlights with 12 awg. Be sure to ground the lights with 12 awg also.
