Question:
I have a Mercedes GL350 Bluetec diesel, and I bought a 1644406434 factory cable that connects to outlets on the vehicle. After installing it, I found that the cable has a 6 pin connector on the outlet side. Does Curt make an adapter that will plug into the connector?

Expert Reply:
Hey Michael thanks for the information. I checked with Curt and Tekonsha and neither of them make a harness that will connect to the 1644406434 cable you got from Mercedes.
The only option I have to install a 4-way connector to your vehicle is the Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector item # C59236. This is a universal connector that has to be spliced in to your factory tail light wiring.
If you have any additional questions go ahead and throw them into the comment box below.
