That is what that Curt cable connects to. Some folks just let the wire hang out the back door but I needed it for my camper that has electric brakes. Needed to fish it to the outside world.You guys know there a pre-wired trailer connector hidden behind the rear panel, inside the van on the driver's side? Pepboys had the male connector that fit with a trailer connector on the other side. Probably the Honda dealer or a trailer supply would have it too.
