My euro headlight main bulb has 3 connectors in a U shape, my car has 3 wires(white, yellow, brown) Hooking this up through relays, which wire goes where on the main bulb? or does it not matter?
secondly, the diagram i got from this site has black, brown, yellow. My car has brown, white, yellow.
Brown is ground?
black(or white) is headlight(lo/hi)?
yellow is headlight(lo/hi)?

Lastly, hooking it up can be done with 2 relays total, one for low beam one for high beam. This means that I will not use one of the 2 headlight main connectors which came out of the US lights, wright???? And I will leave those 2 small connectors from running light hanging if i do not use them???? So from the total of 4 connectors which came out of the US headlights I am only using 1?????(which runs through 2 relays to both low and high beam??

thanks

yes, but that means I am using 2 relays total and hooking up only one side of the original headlight wires. Because I go from the relay to both headlights?

Yes.. You only need one side of the original headlight wiring. All that this (existing) wiring will now be doing is controlling the the headlight relays.

Yes.. The actual 'new' power source for the headlights is the relays. Power now goes to both headlights from the relays.
