I am going to wire up my overhead modules which are mainly from a 727, but not sure if I should use 8/8/8 or the 0/16/16....does anyone have any opinions? thanks.

Use the 8/8/8 only if you planning on using analogs too. 8 analogs8 inputs8 outputsOtherwise the 0/16/160 analogs16 inputs16 outputs

Thanks Matt for the info...but what is analog? Is that for switches and knobs? THanks again.

Potentiometers, i.e. for Throttles, Yoke (in my case SideSticks), flap controls, spoilers and probably all sorts of things I haven't thought about:)
