I have installed a few Trimetrics 2025 and Xantrex Link-pros. Your plan is good. (If I understand it correctly.) You should only connect to the load side of both the Trimetrics shunt and the disconnect switch.
Always avoid connecting things to battery terminals. There are two reasons for this:
1 - Corrosion is an every present issue around batteries and extra connections just makes it worse.
2 - When batteries have to be serviced or replaced, it is never a good time and extra connections have a good chance of getting screwed up.
(Do I Need to add a BTDT to the above? I did a lot of boat work before the depression and batteries and the associated screw-ups were a large part of my income.)
