Here is the basics of a 12v trigger relay, you will need 2. One for high beam, one for low beam. Mount the relays some where that's convenient to you, I prefer the core support. Pin 85 are ground, so run these two to a good body/chassis ground source, pin 30 gets voltage directly from the battery for both, pin 86 is your trigger wire, this will flip the relay once you it receives a signal, one relay will receive Low beam which is a Tan wire and the other is for high beam which is a Light green. The last pin is 86, which is your signal out, this will run to the headlight socket/fitting its self, tan is Low beam, light green is high beam. Now these tan/green run into the driver side socket and back out to the passenger side all you have to do is splice the two together on the out side of the relay (pin 86).
