all you need is a 4 pin relay a diode and some wires and some terminals.
step 1 - locate the Aux. post on the fuse box in the top right corner of the engine bay.
step 2 - attach a ring terminal to one wire and attach it to the aux. post (+)
step 3 - measure about 1 foot of wire out and attach another terminal (pin 87 on relay)
step 4 - locate a ground(i used my alarm hood switch)
step 5 - attach a ring terminal to another end of wire (black/ground)
step 6 - attach a terminal to the ground wire (pin 85 on relay)
this is where it starts to get tricky
step 7 - pull the high beam headlight pig tail and locate the + wire (light green)
step 8 - splice a 1 foot piece of wire to the high beam + (light green)
step 9 - soldier the diode to the end of that wire (make sure its the correct direction(only allows current one way))
step 10 - soldier another piece of wire to the other end
step 11 - attach a terminal to the end and attach it to the relay(pin 86)
step 12 - pull the low beam terminal and splice a wire to the positive (tan)
step 13 - attach terminal to the and of that wire and attach to pin 30 on relay
and your done, some one can double check this
