Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring - no cutting or splicing required.
Features:
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the rear bumper on the driver's side.
Once installation is complete, the 4-way flat 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.

Today we're going to be taking a look at part number 40105. This is the Hopkins Plug In Simple Vehicle Wiring Harness with a 4 pole trailer connector. This is a plug in simple wiring that is going to provide a no hassle quick and easy way to wire your vehicle. The product is designed to fit the Ford F100, F150, F250, and F350 models from 1973 to 1979. It's going to feature the pre-wired design that's going to use the original OEM connectors on your vehicle for a nice water-tight connection. It's going to offer water-tight protection. It's going to offer a guaranteed fit, and it's also going to look great at the back of the vehicle. With this system, you don't have to worry about cutting or splicing or taping any wires for the installation.
You're going to have the four pole connector here on this end. That's also going to include the dust cap so that when your connector is not being used you can simply place the dust cap over the connection points, and it's going to protect them from the elements, keeping out any dirt, grime, or moisture. Then on this end, you're going to have another connector, as well as your white wire. This is going to be your ground connection. When it comes to the installation, you're going to need to locate the tail light wiring harness, disconnect the vehicle tail light wiring harness, and then plug each end into this connector right here. Once you have that done, this connector simply plugs into this connector right here, and then you need to make your ground connection.
White wire, you can use the included self-tap in screw. Once you have that connected, really the installation is complete because now you're able to connect this to your trailer and to send back the signals from the vehicle to power the signals on the trailer. They do include a couple zip ties that way you can secure any excess wires up and out of the way, and they're going to supply a terminal grease packet. It's always a good idea to apply a small amount of grease to your electrical connections. That's going to help prevent any type of corrosion from being able to settle into those connection points. The other neat thing that I want to mention is that it comes with nice detailed instructions in the packaging that's going to walk you through the entire installation process step-by-step. That's going to do it for today's review of part number 40105. .

I was told by my local mechanic that this product was not available but etrailer had it to me in no time! No splicing wires necessary. I had trailer wiring on my 1979 f350 within 5 minuets of opening the package from etrailer!
This is my second time doing business with etrailer and most definitely will not be the last!
This product is plug and play and off to make money $$$
Hitch arrived quickly without damage. Installation on a 1978 F-250 was quick and painless. The harness/plugs with on line instruction were easy to installed.
Worked as advertised. Had it installed, tested and removed in less than five minutes. I'm only planning on using it when I have a trailer hooked up since it's so easy.
