We now support all of the subaru cruise switch types. The V10 and earlier had a bit of an odd setup that used 3 DI's, one for "cruise on" then 2 others in a binary like combination to achieve the 3 set/resume/cancel functions. This type is labelled "Subaru Cruise Switch" in the software and we have supported that since G4+. This sounds like possibly what the XT has.
The V11 and later has a DI for the "cruise on" switch, then an analog with varying resistance/voltage for the set/resume/cancel. We have only recently added support for this one in the last year or so (G4X only). This type is labelled "Subaru 3 wire" in the software. To convert the resistance into voltage the analog input needs a 1kohm pullup connected - or you can use a temp input instead which already has the pull-up internally.
We also support the fully analog type that uses a single wire that outputs different voltages for each button (common in nissan & toyota), and the old school fully digital type where you have 4 digital inputs, 1 for each button.
