Question:

Does the "7-way socket on the vehicle" have the same type connector as the new end ? In other words if I have existing plug , but no socket, can I just plug into this new arrangement. Perhaps you have a picture of the inside of this socket ?

It sure does George. The T-Connector Vehicle Wiring Harness item # C55774 plugs into what's called a USCAR connector. This connector is at the end of the factory wiring on vehicles sold in North America with factory 7-Way connectors and towing packages. I attached a picture below for you.

The T-Connector Vehicle Wiring Harness item # C55774 is designed as a replacement for a factory 7-way connector. It'll plug right into your vehicle's wiring and provide you with a new 7-way and 4-way connector. The included mounting bracket will allow you to attach the new connector directly to your vehicle. If you do not want to drill, you can use the No-Drill Bracket item # C57202 to attach the item # C55774 directly to your vehicle's hitch.

What year, make, and model vehicle do you have? Feel free to answer this and throw in any other questions you have, where it says Add Comment.

@Ellis That's good to know Ellis. I've heard of that issue with European vehicles but wasn't aware there were Grand Cherokee's that had to have the ECM flashed as well. At least they ran the tow package wiring for you. Thanks for sharing that feedback.

@Ellis Glad we were able to get you set up with that hitch and 7-way connector. I have that same hitch on my Durango and the best part about it is I never see it because it's completely hidden behind the rear bumper. It got discontinued last fall when Draw-Tite's parent company filed for bankruptcy so you probably got one of the last ones.
