Tekonsha 3063 P Harness Review

I tried this on Mercedes GL and it is NOT compatible. The wiring should be different than the Sprinter, but is not consistent for Mercedes.

The wiring harness was the perfect length and the connector matched the existing wiring exactly. Save real-time time and eliminate the guesswork of brake control.

The product was great, it's the factory plug placement, it's a bitch, it's under the driver's seat. Just a note, be prepared for a little more work than expected

Worked great with pre-wiring under the seat. I've used a different brand of controllers but it just needed connecting the wires. Just what I needed to add brake control to my RV.

Worked fine in my 2016 Sprinter 3500 with factory tow package BUT power is ALWAYS ON. There is no switch and the MB wiring harness is "hot" whether the key is on or not. It hurts to unplug the controller cable every time I find time to install the switch.

Installed on my Sprinter 2022 which came with a tow pack. The seat was removed to gain access to the factory seat belts. It took some time to find him as he was buried under all the cables. Just look for the green plug. I would recommend watching one of the YouTube tutorial videos to get an idea of what you need to do.
