It goes through the same hole as the umbilical cord.
But maybe the PO did something different. If you have to drill another hole its no big deal.. the jack on the left in this photo is for solar panel
input and uses a second hole that I drilled. The wire to the battery is the smaller, almost white one behind the umbilical (black), and it is wrapped.
Use a grommet and sealant, or other way to protect the wire and keep it water tight.
Dont forget the fuse as close to the battery positive terminal as you can get it.
I like using this:
Amazon.com: Blue Sea Systems 30A MRBF Terminal Fuse
But of course Scamp uses a cheaper fuse and holder.
