Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area on the driver's side and passenger's side. You will have to remove the rear threshold, the cargo nets, and some interior paneling to access this harness. Once you've plugged in the connector, run the red hot lead up to your car battery. Connect the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


Once installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


Powered Tail Light Converter

A tail light converter is built into this T-connector. This converter is a battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.

Today we're going to be taking a look at the Hopkins Plug in Simple Vehicle Wiring Harness with a 4 pole flat trailer connector. This product fits a 2009 to 2012 Toyota Matrix, 2009 to 2010 Pontiac Vibe, and a 2011 to 2012 Scion XB. It's going to provide your four-way flat connector at the back of the vehicle to power your trailer signal lights. This is compatible with 5 pole, 6 pole, and 7 pole adapters. Adapters are sold separately. It comes with a dust cap, that way you can cover up the connection points here on the plug when it's not in use.

The unit also features protective connection terminals to resist corrosion. It's going to include your tail light converter, this is going to ensure your vehicle's wiring matches that of your trailer's. The power module connects directly to the vehicle battery through the wiring to avoid overloading the vehicle's electrical system. This is called the circuit guardian, it's a weather-proof double mold design. It simply protects the tow vehicle and itself from trailer short, so it's a really nice design, built in and included. The overall harness, the overall unit is designed to install quickly and easily.

All you have to do is locate the connection points in the rear cargo area. The kit also comes with detailed installation instructions to help you with the process. Then you're going to have two sets of connectors, one for the driver's side and one for the passenger's side. These are custom fit for your vehicle, so they're going to match up perfectly with the plugs on the vehicle, and they're going to snap together for a nice, tight, secure fit. Once you have those connected you'll need to mount the tail light converter.

You can do that using the slots here on the side and the cable ties provided with the kit. Then you'll need to make a ground connection. Your ground wire is your white wire, it has a ring terminal already attached to it. You want to get that grounded to a nice clean metal surface with the included grounding screw. Then you'll need to run the hot lead to the vehicle battery. The hot lead is a short red wire coming out of the converter box.

It's got a butt connector already attached to it. This gets connected to one end of the bundle of red wire, the other end of the bundle runs to one half of the fuse holder, and gets connected to the wire with the butt connector on it. The other end of the fuse holder has a ring terminal attached to it, that gets connected to the positive post of the vehicle battery. It also comes with your 20 amp fuse, it goes right here in the fuse holder, and it's got the cap on it to keep the fuse safe and protected. Once you have that done, you can use the additional cable ties to secure any excess or slack in the wiring. Once your installation is complete, the four-way connector is going to be stowed underneath the vehicle near the trailer hitch. We do want to recommend using a mounting bracket to keep the connector easily accessible as well as secure. Mounting brackets are sold separately, so if you're in need of one you can check out some options here at etrailer.com. It's also recommended that you use a small amount of grease on all your electrical connections, like the plugs on the vehicle and the four pole connector itself. The grease is designed to help prevent corrosion to the connection points, and it's included in the kit also. 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.
