Did your factory hitch include an adapter to hook up the trailer lights or did you have to buy your own?

Also did the dealer need to program the ML or was it programmed at the factory?

Thanks

There is an industry standard seven contact connector on the factory hitch.

Thanks.

Bought the 7 to 4 pin adapter and everything is working fine.
The voltage present (at the socket) when the vehicle is off is just residual.
