Tow Ready T-One Vehicle Wiring Harness by Draw-Tite, Hidden Hitch and Reese
Can be used with 5-pole, 6-pole or 7-pole adapters.
Installation: Connection points are located behind the vehicle taillights. The 4-pole trailer connector will be stowed under the vehicle close to the trailer hitch. A mounting bracket is recommended.
Tech Tip: It is always a good idea to apply a small amount of grease to all electrical connections to help prevent corrosion.

Today on this 2010 Buick Enclave we are going to be installing wiring harness part number 118450. We are at the rear cargo area of the Enclave, and we are going to locate the ports that we are going to be plugging our wiring harness into. These ports are actually located directly behind the tail light assembly on both the driver and passenger side. So, the first thing we want to do is remove both tail light assemblies. To do that we are going to open up the rear cargo door, there are two inboard screws holding the tail light into place. We need to pull back the covers to expose those. :30
With those two removed we just want to take and rock the tail light back and fourth, there are a couple outboard side clips that are holding it in place as well. With that pulled back, you can see the connector that we are going to be plugging our wiring harness in line to. What I am going to do at this time is disconnect the two, you can do that by pressing the tab at the top here and then pull the two pieces apart. Now I am going to go over and do the same thing for the passenger side light as well. 1:06
Then we are going to start on the driver side of the vehicle, and start plugging our harness in line. On the driver side we are going to be plugging in the port with the yellow and brown wires in them before I actually plug my tail lights back in. We are going to do a couple of other things first, you can see we have a white wire here with a ring terminal on it, that is our ground wire. We need to secure that to the metal on the backside of the tail light assembly. We are going to do that by using the self tapping screw that is provided with the installation kit. Next, we need to take the plugs for the passenger side, along with the 4-pole itself, and feed it down between the opening of the body and the bumper here. 1:44
This space is a little limited though, so to help give us more working room we are going to take off theses two inboard side screws holding the bumper in place. Next, we can start feeding our wires below. With those routed through, I can put these two screws back into place. Then we can plug the other end of the harness back into the tail light. With that done we can put the driver side tail light back on. Now we can move underneath the vehicle and start routing our wires into place. Back up underneath the vehicle, what we have done is take our passenger side connector and our 4-pole wires and routed them up and over the bumper bracket. This is going to help keep it away from the exhaust system. From here I am going to take a 4-pole end and route it to the center of the vehicle. I am going to tie it off at the trailer hitch. Then I am going to take the passenger side connector and route it all the way across. Again, we are going to go up and over the bumper bracket over here as well. 3:17
With it up and over the bumper bracket I am going to take and feed it through the same opening between the bumper and body assembly. Then we will attach it to the passenger side tail light. To aid in the fishing of the wire up to the passenger side tail light, what I have done is route a piece of black gauge wire from the tail light assembly down. I am going to take and tape my harness to it. That is going to allow me to pull it up into place much easier. Then we can just plug our harness in line. From there you want to do a quick double check underneath the vehicle, you want to make sure you do not have any loose or hanging wires that can get pinched or damaged. And your installation will be complete. That will complete the installation of wiring harness part number 118450 on a 2010 Buick Enclave.

I did the wiring harness and trailer hitch receiver myself. I'm not that handy around cars however it between the 2 things, it took me about an hour to instal myself. I didn't have anyone to help me- if I did, it probably would have shaved off maybe 15 mins and less likely to have something fall on my face. Overall, very easy, instructions were great. I installed this on my 2012 Chevy Traverse. I saved a bunch of money- best deal around that I could find!!26588

EXCELLENT PRODUCT, PURCHASE,SERVICE AND SHIPPING. TOWING PACKAGE ARRIVED BEFORE EXPECTED DATE. MOUNTING OF HITCH AND WIRING WAS AS EASY AS DISCRIBED. AFTER TRADING IN A PICKUP TRUCK AND PURCHASING A BUICK ENCLAVE I NEEDED AWAY TO TOW A TRAILER JUST IN CASE I WOULD NEED TO HAUL MY MOTORCYCLE. THIS TOW PACKAGE IS JUST WHAT I NEEDED. I WILL PURCHASE FROM THIS BUSINESS AGAIN.22508

Had a lot of trouble putting wire harness over the bumper bracket as stated in the video. The person doing the video ( I had my computer alongside me under my 2011 Buick Enclave) seemed to just be doing this with his hand. After a half hour of that I tried another half hour of using a fish tape to pull it through. Still no luck. I took a mirror to look at the opening and it didn't look even close as to getting the plugs through so I gave up and installed the harness using a different route with a lot of ties to keep it off the exhaust system.22346

The process for install could not have been easier. I watched the video once and did not need to refer to the instructions. Also can not say enough for the prompt service. I was leaving for a trip on Friday, ordered the wiring harness on Monday, received the package on Tuesday. I will definately use etrailer.com again.20686

Little harder to install than the T plug on my 93 chevy pickup. Getting the pass side plug up between the bumper and the body, I had to use a wire to fish the plug and wire to the opening. In all it's alot easier than spliceing and tapeing the wires.18889

Very easy to install, and you get exactly what you ordered. I had nothing but trouble trying to buy a harness for my 2009 Chevy Traverse. My Chevrolet dealer couldn't find the harness and sent me the wrong part time after time. I ordered from E-Trailer and had the correct harness in two days, and for less money than from my dealership. Excellent customer service and follow up. Thanks E-Trailer! 17978

A very quick and easy install, however, for a 2009 Traverse the wire for the passenger side could be 6" longer. 16927

It was easy to install, and it looks just like the picture. The only drawback was that the supplied tie wraps weren't long enough to go around the tube of the U-hual trailer hitch-not something that they should have foreseen, just how it worked out for my particular application. The electrical connector plugs worked just fine-very plug and play- except that I did need to drill a hole in the sheet metal to mount the ground wire.6771

Would have rated this excellent but the passenger side wire is just long enough with no room to spare. Another foot of wire here couldn't hurt.6363
