The headlights are plugged in through a special connector located on the radiator support (see arrow). While the kit would have let us route the wire differently, we chose to use this connection because the entire headlight grille assembly must be bolted to the front sheetmetal as a unit. This will require a wire disconnect for the headlight grille assembly. The kit supplies the original mating disconnects for this purpose. We also chose this location to mount an electric fan relay.
