Quickly and easily install a 4-way trailer connector on your Ford Edge with this custom wiring harness. T-One connector plugs directly into existing wiring. Powered ModuLite reduces strain on wiring system.

Installation
This custom-fit T-One connector plugs into your Ford Edge's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness.

Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse.
Once installation is complete, the 4-way flat connector will be stowed either within your rear cargo area or beneath your Ford Edge, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure if you are mounting it near the hitch.
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.
A ModuLite power module is built into this T-One connector. With a ModuLite, your trailer's lights will be powered without overloading your Ford Edge's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

Videos are provided as a guide only. Refer to manufacturer

Today on this 2009 Ford Edge we are going to be installing wiring harness part number 118551. We are at the rear cargo area of the vehicle here. And we are going to go ahead and point out the mounting locations for our T- Connector. The connecting points are located directly behind the tail light assemblies. But to gain access to those we are actually going to be routing the wire from the interior, out through the grommet behind the tail light and then making our connections. So to get started we want to go ahead and disassemble the rear cargo area so that we have room to route our wires across. See I have already removed the cargo cover here. Okay then we also want to remove the rear threshold piece here and you can do that by just gently prying up on it to release the tabs that are holding it in. And that is going to allow us to pull back the interior panels here on each side. We want to remove the screw here at the end. We are going to do the same thing on the passenger side.
Now we are going to go ahead and remove the tail light assemblies. There are two inboard screws on the assembly itself that need to be removed that allow us to take those off. And you just want to gently rock it back and forth until you get the outboard clips to release. And with that removed you can see the large connector here. That is the one we are going to be connecting our T- Connector ring to on both sides. To get the wires from the inside to the outside we are going to need to put a little slit to the grommet here. Okay, now we are going to do the same thing for the driver- side tail light. Now we can go ahead and take our harness and feed it from the inside out. I am going to start here on the driver side. We want to take the set of connectors with the yellow and brown wires as well as the white wire with the ring terminal connected to it.
We also want to take off of our modulite box, the red wire and go ahead and connect it to the large, black bundle of wire that is included with the wiring harness. That black wire is also going to come out through this grommet here on the driver side and we are going to take it and route it up to the battery. Take and feed the other end of the black wire out through the grommet. I am going to go ahead and make my connection through the driver- side tail light assembly now. To do that we just want to push the tab here and then just pull the connector off. And we will just plug our harness in line. We are also going to want to go ahead and ground the white wire. We are just going to ground it to this metal surface here using the self- tapping screw that is provided in the installation kit. And then the last thing we want to do here on the driver side again is to run our black wire down through the opening. And that is actually going to be coming out down behind the mud flap here behind the rear tire here on the driver side. To do that we need to remove a few of the screws here that are holding the mud flap on. And we want to make sure we pull the full length of wire all the way out. I am actually going to feed that to the inboard side. We are going to be running it all the way up to the battery. Then we can go ahead and reassemble the mud flap and the driver- side tail light assembly.
Now that we have got the driver side put together we can go ahead and route the connector over right up behind the panel and make our connection in the tail light. And then we are going to slide the grommet back in here. Okay and the last thing we want to do before we route our wire up to the battery is to go ahead and mount the modulite box here to the inside of the vehicle. As you can see we have got double sided tape here on the back side of it. And you just peel that away. You can just peel away the cover here and you just want to adhere that to a clean, metal surface somewhere back behind the tail light assembly. And then with the 4- pole left over in here, leave it stored inside the rear cargo area here and you can pull it out the back hatch of the vehicle when you want to use it. All right now we can reinstall the interior of the vehicle and we will go underneath and route our wire.
Okay when routing the wire up to the front through the battery you want to make sure that we avoid any possible pinch points or hot spots that could damage the wire. All right now we are up under the hood, and you can see we have got our wire in all the way up to the battery. The next step is to go ahead and connect it to the positive terminal of the battery. Pull the cover back here. You can see we have got two auxiliary posts that we can connect to. And go ahead and loosen the nut on that. And next we are going to take our fuse holder that is provided with the harness. We are going to go ahead and just cut it in half. With one end connecting directly to the battery and the other end connecting to the black wire. We are going to strip off some of the jacketing on both ends. And one end we will apply the ring terminal, to the other end, a butt connector. Determine how much length we need of the black wire. And go ahead and cut that down. It will not hurt to put a little bit of tape around the connection. And then finally we will go ahead and add the fuse to the fuse holder. You want to tie up any lose wires you may have left over with the remaining zip ties and our installation will be complete. Part number 118551.

Install took longer than "advertised". Instructions supplied were not very helpful. However, the online video helped much more. The most time consuming parts were removing/reinstalling interior panels and running the hot wire up to the battery. After 1.5-2 hours, we finally had it installed on my 2010 Ford Edge and all lights worked (both on car and trailer).80380

This installation was on a 2012 Ford Escape with back-up sensors and rear view camera. Received the harness when promised and all the pieces were there. The enclosed instructions are a little brief so I viewed the etrailer.com video for the installation which was quite helpful. Took a little over an hour to install working by myself. I liked that the harness wiring was plenty long enough, but not so much that you had to bundle up the extra. Tested after installation and everything worked as it should. I mounted the box on the frame with the attached pressure adhesive tape. I think it would have been a more permanent install if it had a metal band around it for attachment. Used all the included wire ties plus another 8 or 10. Would be nice if more were included in the kit. This is the second product I've purchased from etrailer.com. Each time they ask questions about your installation to make sure you get the product you need. They deliver the correct equipment and it's delivered when promised. You can't go wrong using these guys.72154

Product was fine And install went fine save one issue. The instructional video said to stick the modulator unit to the inside of the bumper and THEN connect the black power lead. The lead was too short to connect at that point since you can't get both hands inside the bumper Either the video should be changed or the black lead coming off the modulator needs to be long enough so the connection can be done outside the bumper and then stuffed back in. Thanks57736

Easy install. Connectors are OEM quality. Not having to splice into existing wiring was very nice. The only negative part of the process was running a 12V supply line from the battery under the vehicle back to the tail lights. There should be a closer supply solution available. Works great.57059




by: Max R.10/11/2012
Is this review helpful?
Great product simplifies trailer wiring with no splicing needed. The only time consuming part is running a 12v power wire to the light controller module. If you're real picky (like me) you will spend more time dressing the wires than installing the trailer hitch. 57019

Is this review helpful?
Easy to install and all the parts are there. Installed it with some friends over some beer and MNF so it took a little longer than what was listed. Wondering though if there is a different wiring harness kit for an Escape with AWD like mine. Ford has a connector for trailer lights that you could have easily spliced into rather than run the main power up to the battery. Regardless, it was easy to install and the videos are accurate and so easy to follow. The only thing I have to figure out is why my LH turn signal blinks faster than the RH. IF someone can tell me that would be great. Otherwise, I'll just have to deal with it. 55027

worked Great and easy to do. just wished there were a plug in pigtail for 2012 e-350 brake switch,or a better way to hard wire brake controler,switch is hard to get to,and it has 4 wires,what Wire is it and how do you unplug it,seems like a good place to use a mercury switch were you would not have to cut into truck brake wire.just clip onto brake pedal arm.54126

The wiring harness for my 2011 Ford Escape Limited was literally a snap to install. The instruction video was right on. Anyone who can change a light bulb or bake cookies can do this. The local price quotes for wiring my hitch ranged from $50-$90 for the labor alone. Total wiring time for me was 45 min. Excellent product and fine service from Etrailer...I recommend them to everyone. 36333

Easy "plug and play" install. Hardest part is running the power wire from the battery to the rear of the vehicle. Factory claims it is a 45 minute job , it took more like 1 1/2 hour, for just the wiring. Buy different wire connectors (splice connectors) for the power wire the factory one are cheap and do not clamp the wires firmly. Also the battery connection end has a hole to small to go around the battery terminal. 33298
