Video Transcript for Hopkins Wiring - Trailer Connectors - HM46370 Review

Today we're going to take a look at the Hopkins Endurance Power Taillight Converter. Now, this system will allow you to install a four way trailer connector on your vehicles. It's equipped with pulse with modulation, independent bulb system, or a common bulb system. The module portion right here is what'll get the signal from the vehicle wiring system, but it will power the lights on the trailer directly from your vehicle's battery. This will also protect your tow vehicle, electronics, and even itself from any wiring shorts, because it uses a self-resetting short proof protection. Also, there's no heavy duty flashers required on your vehicle. On the four way, if you'll notice it'll have these LED lights right here that'll test each electrical function on the four way and it does use this dust cap that'll protect the four way.

When you plug it in just plug it in, and when you're not plugged in just put the cap back over it, protects it. Does use a double-molded weather-proof design. This will provide brighter bulbs. Also has the printed water functions on the wires of the four way right here. It includes everything laid out here on the table. Has the power converter.

It has this extra 6 foot length of 12 gauge powered lead wire, and that is what'll run to the vehicle's battery to supply power to the module. Here's your power wire, you connect it. Now, before you connect this to the battery you want to run it through the included inline fuse holder, has the 20 amp fuse in it. Also has the four spliced gel connectors. Those are used to connect the wires to your vehicle. Has a self-tapping ground screw here, and what that's needed for is this white wire with the eyelet that comes out of the module, need to connect that to a good clean ground, so they do include this self-tapping screw to do that.

It includes some cable ties to take up any slack in the wiring. The last thing is this packet of dielectric grease or terminal grease, and you want to use that grease on any of your electrical connections that you would make. Now, this will power up to 8 amps per output. That should do it for the review on the Hopkins Endurance Power Taillight Converter.
