Excellent Product
Tekonsha® - T-One Connector with Upgraded Circuit Protected ModuLite® HD Module
Excellent quality wiring kit. Love these T connector type kits because if you ever have a power train warranty issue you can remove them without a trace, and they can't accuse you of towing with a car that isn't tow rated. "That hitch? No I don't tow, its just for my bike rack, see, no wiring" Took a couple of hours, most of that was getting the power cable routed up to the battery. Advice for installation - route the power cable to the battery through the interior of the car, don't try to go along the exterior, there is no good place to secure it underneath.

Touareg Wire Harness.
The harness looks very easy to install and comes with detailed instructions. I installed a hitch on my car so I was ready for installation of the harness. The tricky part was fishing the wire through to the battery lead under the hood. It works well so far so pretty happy hope it lasts. Shipping was good although had to make sure someone was at home. Fedex doesn't leave the parcel unless some is there to sign. Makes it tough when you live a hour and a half from the depot. All is good though sure can't beat the price.

Wiring Harness Works Well
Tekonsha® - T-One Connector with Upgraded Circuit Protected ModuLite® HD Module
I've only installed generic wiring harnesses previously; you know, the kind where you have to cut and splice wires. I was very glad to find this one, where you, in essence, insert the wires between connectors the vehicle already has. The system works well. All the lights on my trailer worked the first time I tried connecting it to the system. Also, I like the fact that this system will not overload the vehicle's original wiring system. Even though this is the system specified for my vehicle (2014 Kia Sportage), the instructions missed informing the user about a panel under the vehicle that had to be removed. The panel is on the driver's side, just in front of the rear bumper, and is removed by removing two screws. If you don't remove the panel, you cannot find the t-connector that is under the vehicle. Once I figured that part out, the installation went well. Of course, it would have been easier if I had been able to raise the vehicle off the ground a bit. In any case, the wiring harness works well and I am very satisfied with it.
