I have an older MK Maxxum with a transducer in the foot that I'm trying to connect to an Eagle Cuda 350. I ordered the Lowrance/Eagle six pin adapter, thinking this was the ticket. The problem is the cable I ordered has a 4 hole female side and the plug out of the TM foot pedal is a 3 pin male end.

3+4 don't add up.

Somebody HEP me. banghead
