What Towing Setup Would Work For My 2012 Mercedes Sprinter


Hi, I need a 7 pin wiring harness and a brake controller for my 2012 Mercedes sprinter Cab/chassis. I will be towing a 6000lb foodtrailer with electronic brakes. I might also need a hitch, but my flatbed might be too long for the original mounting points. Or is there some kind of adaptor. Can you help me choose the right parts, please. Thank you in advance!

When installing there is a few parts you would need to start the installation. For the vehicle side you would need to start with part # 118650 which would give you the beginning 4 flat plug. From the 4 flat plug you would need part # ETBC7 which would make the 4 flat into a 7 round, and also giving you the additional wiring needed to activate your trailer brakes.

On the trailer side part # e99011 would provide the attachment to plug into the ETBC7. For the brake controller part # TK90160 would work great with your setup and comes with the needed harness for activation.

With your Sprinter having a flatbed we would not have any options for hitches that would fit your vehicle, but part # 41990 may work but you would need to get the correct weld on bracket kit which is either # 4907 or # 4916

If you have any further install questions here is the two wiring instruction links.
