1941 Scout Corbin vs. Stewart Warner Speedo

[41indian]

Does anyone know if I can connect a Corbin Speedo to a 1941 Indian Scout 741? I am not so concerned that is is not the stock set up but more concerned that most are expensive and I want to make sure I can make it work with the cable and interface. I can't seem to find a Stewart warner and more Corbin's are available.

Any help is much appreciated.
