thanks man. thats the 1 i found too. and what a guy on the main forum said too, must be the right 1. thanks

That is Minn Kota's part number for their MKR-US2-8 cable, which is the correct one for your 161 unit.
So i would say that it is right.

Greg, I am also hooking a terrova US2 to a HB. I have the MKR-US2-8 cable. Wouldn't I also need to order a Humminbird 720003-1" EC W 10" 10-Foot Transducer Extension Cable?

Only if the adapter cable is not long enough to reach to your Humminbird unit mounting location. Otherwise it plugs directly into the unit via the mount or connector collector (depending on the Humminbird unit you have).
