I’m looking for a little help with my 1977 Sea Ray 240 Weekender. I have changed the trim sender switches on the outdrive the limit switch it was self explanatory . The position sender on the other hand is a little bit more challenging, the wires from the position switch go to this block below the harness I assume. There are no other wires to those terminals to be found. The gauge has the purple/white wire and the black wire on it but they are cut off near the rear of the boat and I don’t know how to reconnect them to the sender. Can someone help me out with this question . Thanks for now .
