Firstly, am I right in thinking that there are no aftermarket ignition units for our steeds?

If not, then can any of the more induction-savvy comment on the TCIP4 from this company?

IgniTech.

Will it work with our bikes? Is it an easy swap?

Also, if I buy one of these, I may need to send them a wiring diagram of the connector; does anyone know if the wiring diagram in the Haynes manual is correct? Could I just send a copy of that page?
