## Description

Tekonsha 'T-One', Vehicle Specific Tow Harness Connectors require no splicing of vehicle wires. Simply locate your vehicle's wiring harness connector, unplug the connection and insert the T-One Connector into the vehicle's harness. No special tools required. To reduce the strain on your vehicle's existing electrical system, this kit includes a powered HD ModuLite module that takes power directly from the battery to power the trailer's lighting system. Depending on the vehicle, the module either receives its power from a single, simple to add, wire that connects to the positive battery terminal or draws power from the vehicle's trailer wiring port. The ModuLite module also ensures that the tow vehicle's electrical system is compatible with the trailer's wiring, as well as safeguarding the tow vehicle's electrical system from harmful short circuits and overload situations. Included 4-wire flat connector is compatible with 5, 6 and 7 pole adapters (not included) to fit just about any trailer system. From it's humble origins as a manufacturer of RV stairs and steps in 1964, Tekonsha has evolved to become a trusted name in towing safety. The core product line consists of brake controllers, electrical wiring and trailer brakes. The Tekonsha line has long been trusted by professional towers and weekend warriors for worry-free travel.

Review: Everything connected great. Only thing that could've been better would have been clearer instructions on where to put the grounds too, but easily figured out.
Review: Works great for new 2017 Dodge Durango. Install process is not difficult, but is somewhat time consuming - USE VIDEO from etrailors to walk you through it if you need to. I found that to be more helpful than the instruction page. Generally speaking, I don't trust wire crimp connectors so I went with wire nuts instead - gives me a little more piece of mind with a more secure wire connection. If you have a new Durango, get this and a hitch - no need to pay the $1000+ at the dealer!
