I have just purchased a boat which has a Humminbird 200DX on it and it works great as far as I can tell.
It has three cables coming from the unit - one is the transducer - one is the power cable - But I have no idea what the third one is it terminates in like a sealed pin that looks as though it could plug into something - It is all coiled up and obviously was not used.
Please can anyone tell me what it is - I have the manual but it does not mention it.
Thank You
