How to hook up the battery
 

Went to hookup the battery for the first time to my new to me 2004 sx9 19ft bowrider. I see the large black and large red cables which are self expalnatory and a smaller red and smaller black cable which runs the bilge pump I believe, but there is one smaller cable left over to hook up. What is this for and which side does it go on the positive or the negative.

Thanks

Only way to know is to follow the wire, unless it is black or red???? This sounds like something someone wired in after the factory, so goona have to investigate the wire.

Sorry, no answer.
