Install this instead. Serves the same purpose and allows you to have the house batteries keep the chassis battery maintained.

It's a fairly easy installation and works great! I installed on on my 2018 Outlaw 29H a couple years ago.
Order the Trik-L-Start without the battery clips option as it will be permanently wired.
