You are on the right track. The link below is a book wiring unlimited if you check around page 18 there are some tips and diagrams to consider. It is especially important to wire the bank correctly. For current sharing for battery health.

Sometimes with a 3 battery bank you also may need to consider a bit more maintenance such as position rotation because of the current sharing issue you will run into.
