Whilst cleaning out my garage, I found my MotoGadget instructions & my wiring notes so here goes on the wiring I did to mount it to my 1995 M900 (better late than never, eh?!?)
(NOTE 1: I wired up the Temperature for my low fuel warning lamp)
(NOTE 2: I wired up the Warning light to run off of my side-stand switch)

(*1: Of the factory wires that go into the speedo/lamp cluster there are two black leads. Oddly, the thinner gauge wire is ground and the heavier gauge wire is for the oil pressure sender)
There are 6 wires that power up the MotoScope Light.
