2011 GL450 Brake Controller Wire?
I have 8 days to get setup for a trailer. My 2011 GL450 has a tow package so I think the only thing I need is a brake controller and a wire that goes to the "green plug".
Does anyone know of a place to order with a prebuilt cable? I think I'm going to order a Tekonsha Prodigy P3.
Thanks!
