I have a PK 2004 165 SC. Had it for 6 months. I finally got around to swapping bow mounted sonars with my other boat. Previous owner had the power coming off the trolling motor connectors. To get the job done I just connected mine to the same spots.
My question is: There seems to be a spare unused wire harness right there under the bow deck right next to the trolling motor receptacle wiring. Its wires are orange (maybe faded red) and black. There is a similar wiring harness white and black that is connected to the bow light. I don't know if there was originally something connected to the "spare" wiring or if I can just get a matching connector and have the whole sonar wiring dis-connectable ???? ( The previous has modified the gauges too [ see my gauges on the post about gauges ] so I still don't know if there might be something he disconnected that was originally there ?? ) In the picture it looks pretty white not orange but that's just the sunlight on it.
