Video Transcript for Review of Tekonsha Custom Fit Vehicle Wiring - Trailer Hitch Wiring - TK68DR

Hi everyone, Steven here with etrailer.com. Today, we're looking at our T1 vehicle wire harness with a four-pole flat trailer connector. Now folks, it says a custom fit application, so make sure you're checking our fit guide here at etrailer.com on our homepage where it says My Vehicle Information, enter things like year, make, and model, submodel, cab length, bed lengths, whatever it asks you to be sure you're getting in the right parts the first time. Now getting into it, this is going to, one, protect your vehicle wiring. The modulator box here, as we call it, prevents trailer shorts from causing damage or backfeeds onto the tow vehicle, and it's gonna also draw power directly from the battery using this long length of wire that's gonna get routed all the way up the vehicle, all the way to the battery. Now just follow the instructions that come with it and you'll see that it's not too hard to do.

Now if you're not wanting to do this yourself, you can obviously take it to a local dealer, or on our homepage, you can also link up with some dealers that we are associated with as well. Now you shouldn't have to do any kind of cutting and trimming. It's a quick connect terminal on the backside of your taillights, you simply unplug the factory plug from a taillight with the correct side per the instructions. Plug this one back in the taillight, and then you're on your way. No cutting, no splicing, easy access, and it's gonna give you easy access to the trailer connector.

Once you get it installed, you have your four-pole connector here for the trailer with the included dust cover that goes right on there. You're also gonna get a lot of cable ties, inline fuse, some heat shrink butt connectors for the connection up at the battery and to the back, along with the ring terminal could make that connection as well. Now I do recommend on this particular vehicle getting a bracket to mount this wiring connector, and that's sold separately. You can find that here at etrailer.com as well. Well folks, I think that's gonna wrap it up for our quick look together at this T1 vehicle wire harness.

I'm Steven, thanks for watching.

  • Availability of Wiring Harness for 2025 GMC Terrain With Tow Package
    Hi Lloyd; the Curt T-Connector Vehicle Wiring Harness # C88RV will fit the factory wiring connections. However, it is still a pre-order product and we don't have an ETA from Curt. If you really need a wiring harness you can use the T-One Vehicle Wiring Harness # TK68DR instead. This bypasses the factory wiring by plugging into the connection points behind your tail lights. You will also have to run a hot lead up to the battery.

    Hello Bill, Thanks so much for reaching out about the harness. I just need a little more information from you if you don’t mind. I see that the T-One Vehicle Wiring Harness for Factory Tow Package # TK67KR is the correct replacement if your Terrain has the factory tow package.
