Assuming each of the three instruments is connected directly to its own transducer, and you want to extend those cables
, the depth
is a 3-wire and the speed/temp is a 5-wire cable. I'm not sure about the wind
cable. You most likely have Airmar transducers so if you wanted to retain the color scheme, they would be a source for the cable if you couldn't get it from Raymarine. An easier solution would be to use plain vanilla 3-wire and 5-wire cables and color the individual wires to match the existing (nail polish, colored tape, or a small tag with "red," "green," etc., as applicable). Also suggest you solder the connections, and use heat shrink to insulate.
