Video Transcript for Demco Tow Bar Wiring - Bypasses Vehicle Wiring - DM9523047 Review

Speaker 1: Today we're taking a look at the Demco Taillight Bulb and Socket Kit. Now, this wiring kit is pretty simple. Don't let it get too complicated. It simply lets you display your brake, inaudilbe 00:00:12 and turn signal lights on your tow car without tapping into its wiring. So this type of set up is perfect for vehicles that are being flat-towed by an RV, and you want to get the brake, tail, and turn light signals back to the towed vehicle's taillights, but you don't want to tap any wiring into the vehicle's electrical system.What this unit does, is it allows you to bypass the tow cars electrical system completely because the wiring is routed beneath the vehicle, and then it just hooks up to your RV connections and gets the signal from the RV and then just sends it back to the bulbs in this kit that'll be mounted in the taillights of the towed vehicle.It includes two lights, two sockets, wiring extensions, your 26-foot-long four-way connector. You have your 16-gauge wiring.

When it comes to the four-way, you get all the necessary connectors so you got some butt connectors, ring terminals, and you have your quick splice connectors detailed installation instructions, and some nylon ties to securing the wiring up and out of the way.It's really simple. Basically, you'll need to refer to the installation instructions, and you'll need to drill out a small hole in your vehicle's taillight assembly. And then this goes in that hole. Wiring feeds out the back, and you will want to use an appropriate sealant where the hole is, that way you keep dirt, grime, and moisture out of your taillight assembly. And then these wires, one goes to the passenger's side of the vehicles.

One goes to the driver's side. The wires come down. You can use the extension wires if needed. You got your ground wire, and then you got your taillight wire, and then you got your stop and turn wire. That taps into the four-way, so depending on your application, you may need a cut the plugs off and then hard-wire it, which is why it comes with quick splice connectors and all the necessary butt connectors and ring terminals.Once you have the four-way connected to both sets of bulbs, one on the passenger, one on the driver, then this runs beneath the towed vehicle all the way to the RV.

And then it would plug into the RV or wire into the RV, and then that way when you're flat-towing, again, your signals from the RV are sent to the back of your flat-towed vehicle, and you're not tapped into the vehicle's electrical system at all. Just please note, that the towed vehicle must have enough room inside the taillight lens housing for an extra bulb and socket.So that's going to do it for today's look at the Demco taillight bulb and socket kit.
