FYI. My son had a problem this week with the starter solenoid connector on his 916. I had rake through the various connector bits and pieces that I have and found that the female terminals from a TM connector fit the solenoid connector housing. https://kojaycat.co.uk/epages/950000457.sf/en_GB/?ObjectPath=/Shops/950000457/Products/"2W-BAT-CHGR- CONN"
Thanks Derek, that company are excellent for many Ducati connectors, I looked recently but couldn't find above.
