Review of Hopkins Custom Fit Vehicle Wiring HM11141854

Today we're going to be taking a look at the Hopkins Plug-In Simple Vehicle Wiring Harness with the 4-Pole Flat Trailer Connector. This product fits certain years of the Toyota Prium. You can use the vehicle fit guide located at to make sure this is a fit for your vehicle. It's going to provide a 4-way flat trailer connector at the back of your vehicle, which is going to power your trailer's signal lights. It is compatible with 5-pole, 6-pole, and 7-pole adapters. Adapters are sold separately. It comes with a dust cap for the 4-way flat connector.

That way you can cover up the connection points when your plug's not being used. It's also going to include a tail light converter. This is going to ensure that your vehicle's wiring matches that of your trailer's. Power module connects directly to the vehicle battery through the wiring to avoid overloading the vehicle's electrical system. The unit's going to connect quickly and easily. All you have to do is locate the connection points in your rear cargo area, plug in your connectors.

One connector goes to the passenger side. The other one goes to the driver's side. These plugs are going to match up perfectly with the ports on the vehicle. Once you have those connected, you'll simply need to make a ground connection, that's your white wire with a ring terminal already attached to it. Get that grounded to a nice, clean metal location with the included grounding screw. Then mount your converter box to an out-of-the-way location.

It's going to have two mounts on each side or one mount on each side, two total. You can mount it to get it out of the way with the included cable ties. Just tie it off to something that's going to be a safe area for the box. It's really easy to get mounted. After you get that done, you'll need to run the hot lead to the vehicle battery. The hot lead's the short, red wire coming out of the box.

It needs to get connected to one end of the bundle of red wire. One of the things I like about the wiring system is that the connectors are already attached. The butt connector is already on there. You attach this red wire to one end of the bundle, other end of the bundle connects to 1/2 of the fuse holder with the butt connector already on it. Other end of fuse holder has a ring terminal already attached to it, and that connects to the positive post of the vehicle battery. It does come with your 15-amp fuse. Goes directly into the fuse holder. It's got the cap on there to keep it safe and protected. Once you have that done, you can secure any excess or slack in the wiring with the included cable ties. Once the installation's complete, the 4-way connector is going to be stowed in your rear cargo area. It is recommended that you use a small amount of terminal grease on all your electrical connections like the plugs on the vehicle and 4-pole connector itself. This grease is going to help prevent corrosion to the connection points. It is included with the kit. That's going to do it for today's look at the Hopkins Plug-In Simple Vehicle Wiring Harness with the 4-Pole Flat Trailer Connector.
