Thanks to all who are trying to help. I apologize if i missed out information but i am feeling slightly disillsioned with it all at the minute.
When i brought the mc18 and took the tank off, most of the carb plumbing and one air solenoid were missing. I now have all solenoids and pipework but am missing a connector from the loom.
I have the green connector for one solenoid (Black/White, Pink/White)
But so far cannot find ANY wires for the other solenoid (Black) connector.

I thought it would just be a case of cutting the loom back and hey presto, there are the missing wires taped up waiting for connection but nope, nothing. I've traced the Black/ white, Pink/Black wires near to the battery but theres no trace of any spare wires. Am i in the wrong place?

I've looked at the Dreamgate wiring dirgram but the colours don't match mine and some have question marks on the colours.Err.

Its a bit like trying to complete a puzzle with missing pieces and no box to look at! I confess to being hopeless at wiring problems. I just seem to stare for a while, walk off, come back, stare some more.........you get the picture.

I realise this is pain to solve without actually being there but would appreciate any idea's..........that don't involve petrol and matches.......
