I have a direct battery connection that runs to a 4 fuse panel under the hood
The wiring for 2 runs then goes to a convenient illuminated rocker switch panel in the cab, a 3rd run goes to a CB radio, the 4th fuse in the panel is just extra
From the rocker switches the wiring & plastic loom follow the trucks frame back to the left front corner of the bed to a couple of WeatherPack connectors.
From there a ground & power wire go to my auxiliary gas tank & the other 2 wires go to my rotating lights
You can see the CB radio & 2 illuminated rocker switches in this pix
Here you can see the Auxiliary Fuel Tank & Lights
This is the Weather Pack website
