The middle wire in the grill signal harness is the one that turns the lamps on in the park position, the outside wires are the ground and the one that sends the actual signal blink.

The euro/mach headlights use the "city light" (the little 194 sized bulb) as the middle wire from the grill harness, then the signal wire goes to your blinker..

And the halos usually end up looking a lot better if you don't wire them up at all ;)
