Installation
This custom-fit T-One connector plugs into your GMC Terrain's factory tow package wiring harness, which is located behind the driver's-side interior trim panels in your rear cargo area.
Once installation is complete, the 4-way flat connector will be stowed in an out-of-the-way location within your cargo area.
It is recommended that you use a small amount of grease on all electrical connections - the plug on your automobile and the 4-pole connector itself - to help prevent corrosion.

Today on its 2010 Chevrolet Equinox were going to install part number 118264 from Tow Ready. This is the Wire Harness for vehicles that have a Tow package plug. First thing we do is go ahead and remove the bottom panel here and the threshold. Now the threshold pops up pretty easy from the back side here but many of the tool from the other side to pop it up. Now, the port is located underneath here behind this gray component and in this case we are going to go ahead and listen up this panel on the inside here. To make it a little bit easier to see.
We will go ahead and remove this two type points so we can move up the panel. That support we need to get to plug in our harness. Pop and loosen the fitting from the side, just pop it together, put back in place. Now for the interior back together and the wire harness will stay with the spare tire and we're not using a harness to stay like that. Now, we do need to use it simply pull out.
Just stay away from the latch and then shot the hatch on it. And pull out what you need to go down to your hitch. With that, that will finish it for our install of part number 118264 from Tow Ready.Filename: Page 1 of 1Order #: 144539532 .

Plugged right in to the existing connector on our 2011 Equinox LTZ V6. Unlike in the video, I was able to connect it without removing the panel, tested it with a voltage meter to be sure I wouldn't need the computer reprogrammed as someone else indicated. For now I left it stored right where it plugs in But plan to wire it out through the grommet and into the bumper.59071

I just purchased a new GM vehicle that did not come with a hitch. My expectations of ease in installing this hitch myself far exceeded what I expected. Installation was extremely easy, total time to install was less than 30 minutes. Parts were "high" quality. Instructions were very easy to understand. Shipping was quick and delivery confirmation included. My total experience with etrailer was extremely positive!!!!58528

This harness works great for my Terrain. I like how I can just hide it away in the spare tire compartment when not in use. I had to decide between this and the more expensive, more difficult to install harnesses meant for Terrains without the factory towing package. On a hunch, after viewing the installation video online for the harness with the factory towing package, I decided to see if the factory harness connector was actually in my Terrain. I have the highest-end SLT-2 package, which includes the power rear liftgate and other extra options toward the rear-end, so I thought I might get lucky and find the connector there. Sure enough, after removing the trim panels as in the video and feeling with my hand in the area noted on the video, the connector was there, attached to the sheet metal to prevent it from rattling around. All I had to do is pull it free from the sheet metal and I had all I needed. So for those of you who thought you didn't have this connector without the factory towing package, check for it anyway -- you may likely have it like I did if you have an up-option Terrain.54825
I own a 2010 Equinox 2LT with the 2.4,4 cyl engine, which did not come with a factory tow package not available with the 4 cyl engine. I also checked for the factory harness connector, and found it with no problem. The connector was live and it was a simple plug and play installation. I have heardread that some times the factory connector is there but not live and it requires a trip to the dealer to have the computor re-programed, but that was not the case with my vehicle. My daughter has just ordered a new 2013 Equinox without the tow package and I will be checking it as well... will post a report on that car as well.
