MinnKota MKR-US2-8 Hummingbird 7 pin adapter cable #1852068. Universal Sonar 2 connects trolling motor to your HB. It is 16" long. I bought a MK Terova from BBG 3 years ago and told them I used Lowrance. However they sent me this cable by mistake. I offered to return it if they would send me a pre-paid shipper, but they said just keep it and we'll get the correct cable out to you. Which they did. The cable has never been installed. Cash pickup or free ship with PayPal.
