Can I wire the Truck Bed Lighting Kit to a vehicle switch, how do I use the included 3‑prong switch, and does it include installation instructions?Updated 5 hours ago

Yes — the Truck Bed Lighting Kit can be wired to an existing 12 V accessory switch in your vehicle instead of (or in addition to) using the included 3‑prong switch. The kit comes with its own On/Off switch and full installation instructions showing how to wire it:

• The kit’s power lead from the battery or other 12 V source connects to the right terminal of the included switch.

• The kit’s power wires (with the white stripe) connect to the center terminal of the switch.

• Both ground wires and an added ground lead are connected to the left terminal.

If you choose to use a different switch (like your vehicle’s accessory switch), ensure it’s rated for 12 V and follow its wiring instructions or the kit’s diagram for proper spade terminal connections. The full guide is available here.
