How Do You Wire Truck Bed Lights on a Ram 1500?

Wiring truck bed lights on a Ram 1500 is a straightforward process that requires some basic electrical knowledge and tools. With the right preparation and understanding, it can be done in just a few hours.

The first step is to identify the appropriate wiring harness for your Ram 1500. Most aftermarket truck bed lights are designed to be used with an OEM wiring harness. The wiring harness will provide the proper connections to power the lights, allowing them to be wired into your truck’s existing electrical system.

Once you have identified the correct wiring harness, you will need to route it from the battery to the location of your truck bed lights.

When routing the wiring harness, make sure that it is not in contact with any sharp edges or moving parts. It is also important to use a circuit breaker or fuse in order to protect your electrical system from any potential damage.

Next, you will need to connect the wiring harness and run it through an existing grommet or drill a new one if needed. This allows you to easily run the wires through the firewall without having to cut into it, which can be dangerous and cause damage.

Once everything is connected, you can then mount your truck bed lights onto your vehicle. Most aftermarket lights come with mounting hardware included so all you have to do is follow the instructions provided by the manufacturer.

Finally, you will need to splice into your vehicle’s 12V power source in order to activate and power your truck bed lights. This step requires some basic knowledge of electrical systems so if you are unfamiliar with this process, it may be best left up to a professional installer.


Wiring truck bed lights on a Ram 1500 does not have to be complicated or time consuming as long as you have all of the necessary tools and materials beforehand. With proper preparation and understanding of how electrical systems work, anyone can install their own set of truck bed lights in just a few hours.
