I looked at the schematic of the 77 and it is spread out over several pages

is a "keying circuit" so my hunch is that even though its relay uses 26v, it
probably has 12v keying to the external world. It probably says somewhere
in the manual.
The thing to look at is what the keying output of the Corsair sees. With
luck, that should be the base of an NPN or PNP transistor. If it is,
i'd say it's safe to key it directly.
