The switch unit comes ready wired to the three switches on the switch unit (top left) and three fuses (top middle) (fig 1). All I needed to
All I had to do is take a negative wire (black) and attach it to the negative busbar and a positive wire (red) and connect it to the positive busbar (fig 2): the top wires in fig 2.
Next I took the one available wire from the top switch and extended it by connecting it to a long length of wire wire. The long length was routed up the side of the wheel house and across the top of the forward window. I had left spaces in the wheel house to accommodate the wires (fig 3). I also secured a negative wire to the negative bus and ran it with the read to the nav lights.
The wires passed though holes behind the Nav lights locations and were secured to the negative and positive points on both lights (fig 4).
both light were screwed to the outside of the wheelhouse, the battery connected and the top swith turned to on ... the light illuminated. (fig 5 and 6).
