May sound stupid ,but I just received the transducer extension cable. My question is, how to make the connection? Is there something I need to remove from my existing cable? There is a kind of sleeve that is keeping the pins from seating. I don't like it when a product doesn't come with instructions. Plus I don't want to ruin my connector. All of the places I called are closed. I tried HB's site, Nada! YouTube same thing nothing really available. If you can help I would be grateful. Thank you.
