Last week I picked up some new LED lights for my motorcycle and installed the P3 lights for the tail end of my motorcycle. Installation over all was very easy and I spent more time running the wires than I did doing the actual installation.
Here I took of the tail end of the bike and setup to run the controller from just under the seat. I ran the wiring along the left side of the bike following the existing breaklight wiring as closely as possible.
Here you can see the wire coming out just under the the bottom left side of the rear fender where the existing license plate lighting wire runs from. I basically followed this wire all the way down.
Here is a picture of the LED units mounted on either side of the license plate. The screws and brackets were mounted to the top holes of the license plate.
Here is a closer look of the wiring as it runs down the side of the bike and how I tried to tuck it away behind the rear bracket.
The controller was mounted to the rear frame piece under the seat with some zip ties and I wrapped all of the wires in cold shrink tape in the end.
