guys....

inbetween the gear selector and clutch leaver... there is a plug that goes into
the mc21 block that has sevral wires on it, removing it, you can see it has a o-ring on it, and at the end has small shaft with a key type thing at the end...

on new mc18 block, this plug has nowhere togo as it doesnt obviously fit this unit..


what is it.. do i need it?, engine runs without it...

thanks guys


p.s its a low-milege mc18,
