Tow Ready T-One Vehicle Wiring Harness by Draw-Tite, Hidden Hitch and Reese

Today we are working on a 2008 Jeep Grand Cherokee. Well be installing Tow Ready T-One connector part number 118425. Our first step is going to be accessing the rear cargo area of the vehicle; were going to need to remove the two push pins that hold in the tail lights. Theres two on the passengers side and two on the drivers side. Then go ahead and pop the tail light lens loose and were just going to let it sit here to the side while we go repeat the same process on the drivers side. On the drivers side with the tail light lens removed from the vehicle we can go ahead and remove the large connector.
Were then going to take our new Tow Ready connector, and this will be the yellow and brown wire and plug it in line with the manufacturers connector. Push it in place and reconnect the red locking tab. Well do the same behind the tail light. Okay with our connections made behind the drivers side, we are going to go ahead and take our wire and route it down between the bumper and the sheet metal. This will feed out below down by the frame of the vehicle.
Theres our four pole, and now we will go ahead and feed down the green and white wire, it is going to be routed over to our passengers side. With our wires fed underneath, we can go ahead and reinstall the tail light for the drivers side. Now we are going to get up underneath the vehicle, route our four pole over the hitch and our green wire over to the passengers side. I am going to follow the inside of the bumper here as it will give me plenty of places to take some zip ties and tie it off. Now that we are over here to the passengers side, just like we ran it down on the drivers side we will run it up on the passengers side between the bumper and the sheet metal of the vehicle.
You can see we have quite a bit more than what we will need so well just take some of that and tie it up here with our wires with a zip tie. Now before we go up behind the passenger tail light and make our connection, we need to go ahead and take our ground wire and ground it. Its the white wire with the ring terminal already on it, and we will just be attaching it with a self tapping screw. With our ground wire secure we can not go ahead and get behind the passengers tail light and make our connection. Just as we did on the drivers side, we will be removing the larger of the two plugs, and plug our new connector inline with the manufacturers wiring.
Then we could go ahead and reinstall our tail light. With the passengers side tail light reinstalled, that completes the installation of our new Tow Ready connector, part number 118425. .

I bought this wiring harness as an after thought. I had purchased the trailer hitch earlier in the year to mount a bike rack on my Grand Cherokee and since I do not own anything that needs to be towed there was no reason for having a harness. Since that time I have had to tow a few thing like a Uhaul trailer and a rented log splitter so now the need is there. I have dealt with eTrailer on other occassions and so far EVERY experience has been a good one. When I decided to get a harness I did not spend any time loooking anywhere else. I had read the reviews and although most were positive I did see a few that were negative about the length of this item. I will admit that on my first attempt I also thought that someone made a mistakewith the length. I did take a few more minutes and tried another route and had more than enough wire. As with my previous purchases I am once again a very satisfied customer. Keep up the good work!26768

The product quality is excellent, BUT the 2011 model year JEEP GC has changed. The wiring harness is to short! I had to add additonal wiring by cutting and splicing additional length. This product needs to be upgraded to fit 2011 Jeep Grand Cherokee.16837

I too thought the harness was too short, but it turned out that there is a zip tie holding the passenger side wires to the driver side. You can snip that zip tie off and give yourself some slack. 31060

Quick, easy, good to go! Length not a problem for my 2011 Jeep GC. After this experience with the 118425 I'll never spend $200+ on a factory wiring harness and installation again. Seems the Jeep people can't install what they sell and get it to work so thanks to those who know how to make things simple. 28373

Toughest part was prying off the connectors from the back of the taillights. Easy install after that. Clear directions.21753

Installation of this harness was very easy after I watched the harness install video. Together with this harness, I also ordered from etrailer, a 10 foot long plastic wire loom (PN 39035) which I used to cover the wires before installation. I thought this would insure protection of the harness wiring as it is routed under the bumper. This harness would have been perfect if it came with the plastic wire loom already installed. It only took me a few more minutes to install the loom so no big deal. The harness was of perfect length and all the connectors just snapped easily.20265

Works great and very easy to install but wires could be about 6-12 inches longer which would be easier to het across under the bottom the truck.20065

Have a 2011 Jeep GC- product works great- don't listen to the other reviews about harness being too short. It's close, but you have to watch not to get the small transfer box on harness caught up on anything- that's what it did and I threw a fit, but once I figured it out I had about 1-2in to play with on both tail lamps. The hitch wire/plug has plenty of length- prob about 1ft extra that I zipped up behind bumper cover. I did have to drill a very small hole at the bottom of the rear body for the ground. *Etrailer was very, very fast with the shipping, even with the free shipping. Would definitely buy from again18420

Very easy to install and works great, the only problem is the cover for the pins does not fit very well. 8918

The item came earlier than expected so the service was excellent. The installation was a breeze. Shims were supplied in case you needed them for a tighter fit. It took us maybe 25 minutes total for the installation.8865

The video was great and explained the procedure. With the help of a wire coathanger it was easy to pull the harness up on the right side.I had to run a additional ground wire back to the chassis since my 2011 Grand Cherokee had no place to ground by the tail light housing. Very simple to do.8539

The item arrived quickly and as promised, but it is not designed the best - the wire that runs between the tail lights should have been between 6-12" longer. The fit was just too tight and I was not able to run it exactly where I wanted due to the short length. That being said, I did get it hooked up quickly (20 minutes) and the instructions and video tutorial were very useful. 6213

save me lots of time and money I had bought the factory harness for 104 dollars. Waste of money. You have to have them do it because it needs to be programed. I returned it after they wanted 175 dollars to install it. etrailer got me a harness within 4days it only took 5mins to install best decision ever.3142
