12-Volt Power Supply Kit

Fused 12V power from your battery to the back of your truck, SUV, van, or trailer. You get 25 feet of 14 AWG two-wire cable with a 5 amp fuse already in the fuse holder.

Weather-tight ring terminals connect to the battery, and the far end is bare wire for your Kingpin switch. A tough sleeve covers the first five feet to protect the wire through the engine bay, and zip ties are included to hold it along the frame.

As it comes, it handles up to 5 amps. One Kingpin switch fully loaded is 3 amps, so you have room to spare. You can swap in a different fuse size if you need to.

Kingpin tip

Add up what's on at the same time. An F-Series 40" draws 1.1 amps, and a V-Series 40" draws 1.4 amps.
