Here's another variation on the theme
If you prefer, you can use this key-fob-style wireless remote momentary switch in place of the RFID control box - connect it up exactly same way with the diode-operated latch off the ignition feedback - can also still use the clutch-switch as an enable so both clutch AND remote switch are required to set ignition.
And here's a copy of a system I just drew up for a Sprint user - the circuit is virtually identical for Speed Triples.
This one uses the RFID per the original system but relocates all the control diodes inside the box and also adds the immobilizer relay. All the connections (except clutch switch) are off either the OEM alarm connector or the main key-switch connector.
(Again, the RFID box can be replaced by the Remote Box linked at the beginning of this post.)
