One of the members asked me about swapping out the instruments
On the RIII & classic, you can swap to pretty much anything you like (after-market or even some OEM)
However the Touring & Late Model use CANBUS so not much you can do there.
I created a Key that identifies each of the signal wires at the instruments.
A couple of quick notes:
The indicator lamp signals for Neutral, Oil Pressure, Low Fuel and MIL are all active 'low'
The indicator lamp signals for Turns and Hi Beam are active 'high'
The speedo power 'out' is a switched 12V for the speed sensor.
The Alarm LED are LED voltage level signals i.e. connect directly to a bare LED, not 12V-ready LED.
Hope this is useful for anyone who chooses to go that route - thought that I should just post it up for general reference.
