The Hella part number for the relay I used is 4RA 003 510-182 you will 
need a total of 4 relays - 2 for the low beams and 2 for the hi beams. The 4 
terminals on each relay are numbered - 85, 86, 87, and 30

For first headlite - (requires 2 relays)
1) disconnect the socket from one of the headlite bulbs.
2) splice 12ga wire (or heavier) from the connector low beam wire to 
terminal #86 on relay 1.
3) splice 12ga wire (or heavier) from the connector hi beam wire to terminal 
#86 on relay 2.
4) run new 12ga wire (or heavier) from terminal #87 on relay 1 to low beam 
terminal on bulb.
5) run new 12ga wire (or heavier) from terminal #87 on relay 2 to hi beam 
terminal on bulb.
6) run wire from + terminal on battery to terminal #30 on both relays
7) run ground wires from terminal 85 on both relays to chassis ground
8) connect bulb ground terminal to ground wire in original headlite socket.

Repeat all steps above for second headlite .
