Second can-bus in/outputs on 1.8t BAM plug&play emu black?

[caddymaxi500]

hello,

i have a 1.8t BAM plug&play emu black.
on the back there is a plug for spare inputs/outputs, there is also a second pair of can-bus pins.
but how can i use them and do i have to deselect the 120ohm terminator in the can-bus settings to use them?
can i do like in the drawing that i made?

thanks

If you add termination resistor then yes.
