Hello,

I recently purchased a 2011 ml 350 with no trailer Hitch or trailer wire harness installed on the vehicle. I'm in the process of ordering a trailer hitch from an online website and the installation seems straight forward.

But , i'm having issues finding reliable information on trailer wire harness installation kits.

Can someone please provide me with information on installation and a reliable vendor who sells the trailer wire harness kit..

thanks

J
