I have a 2016 242 x and the dealer winterized it and disconnected the batteries. I need to figure out what goes we’re. Diagrams pic ect.
Please and thanks
 
A photo of mine would doesn't help as much as I've rewired mine (but I added it below for reference).

But here is what you should have:
1 Red wire from switches to your starter battery (closest to the stern). See it below (covered in black tubing at the top of the photo)
1 Red wire from switches to your house battery
2 red wires from your amps to your house battery

The rest of your black (negative wires) can connect to either negative terminal
1 black wire connects both negative terminal together (in my photo I added a negative bus bar and just have one wire to each negative post)
There is a skinny black wire that should say something like DVSR ground wire-it goes to a negative terminal but is easy to miss

Thank you. Is the house battery usually the front one or the rear?
