Seaward was acquired by Whale a year ago... I guess they don't sell the panels anymore...
Or they do?

The panel comes with a terminal block connection and Seward recommends a terminal block for the engine end. Ask for the long wiring harness and you won't need the terminal block kit. With the long harness you can connect each wire,one at a time, from the new panel directly to the engine. Seawards recommendation with the terminal blocks means 3 pieces of wire for each run. Give Seaward your hull number and they will know what you have on your boat. I did have to order a new box to put the panel in from Catalina but it took so long for Catalina to supply the part that I made my own box. I still have the Catalina box if you want to go that route. Seaward advertises in Mainsheet magazine and can be reached at seawardproducts.com or 562 699 7997.
