well then that will be real heat in that headlight eh, just letting you know.
it should be very simple
4 pin relay (use a relay harness as well):
1st pin = switch goes to input for relay switch on
2nd pin = ground for relay switch on
3rd pin = 12v source in for relay
4th pin = 12v out from relay to 1 pin on bulb..........2nd pin on bulb goes to ground
check the relay diagram to see which pins are for the switch and which are for the 12v input/output
if a 5 pin relay is used, simply disregard the center pin.
i did something similar in my lancer when i put in HIDs
