BMV-712 Battery Monitor Install Questions

I'm tech challenged so requesting info on below questions before I hook anything up.

1. Motorhome batteries connected in parallel so:

a. Connect negative cable with accordion shielding to "Load and Charger" lug on shunt?

b. Buy another cable to connect from negative battery post to "Battery Only" lug on shunt? What size cable do I buy? 4 AWG or 2 AWG?

2. Connect positive red cable to shunt B1 for power. Since batteries in parallel no need to connect wire to B2?

Any suggestions on other things to be aware of?

I hope the batteries have identification on them somewhere so I can figure out battery capacity for system setup.

Thanks for your help.

The shunt goes in the blue spot.

Use at least the same size cable as is there.

Yup, battery #2 stays the same.
