Sure - the wires from the things that are monitored (bilge pumps for example) all terminate into a single connector for the OEM Sea Ray Systems Monitor module. That connector can be removed via a single hex socket screw in the middle of the connector.Our SM display crapped out circa May of this year, and I'm still pondering solutions. I've tried simple diagnostics and the reset procedures (for the "newer" SM part numbers than what we have), no joy so far. Not unexpected. And in the meantime, I've been trying to memorize what you've done to replace/upgrade.
In the meantime, some info on "simple" replacement is here:

I haven't even put eyes on our bilge interface yet, and haven't tried bypassing existing coax to see if our issue is relatively minor. Not expecting it is...
Anyway, can you describe the physical connections at the RIM100? Are the existing sensor wires all connected to the original bilge interface module with ring terminals on studs? If so, are the Maretron connections using those same ring terminals on RIM100 studs? Off the old, onto the new?
Or...?

Those same wires will terminate onto screw terminals on the Maretron RIM100 box. So, that connector gets cut off then ring terminals get crimped onto the wires then the ring terminals get installed on the Maretron box. Some of the wires go +24 VDC (in your case) and some go -24VDC depending upon what device they come from. Most like your bilge pumps will go +24 however. So, back on the Maretron RIM 100, there are two screw terminals for each channel and there are six channels. One channel for each device to be monitored. Let's assume you want to know if a bilge pump comes on; the wire will go hot to +24 volts when that pump activates. The Maretron RIM100 will see that hot let's say on Channel 1 but it has nothing to bias it against so consequently, the second terminal on that channel needs to be connected to the battery -24 Volt (ground). If you have a device that goes to ground when shut down unplanned (like the generator's status wire) then obviously you need a +24 volt bias on that second screw terminal for that channel.
The only other connection on the RIM100 is to the NMEA 2000 network.
