Purple plug

Had day off work so was doing a little tinkering under the bonnet of the R. Found a purple plug loose round the back of the block. After much looking and messing aorund I managed to plug it back in right under the air inlet. Have no idea how long its been loose anyone know what it is for?

Its the F.I.C.D. solenoid valve.The F.I.C.D. solenoid is turned on when the ac compressor is engaged so as to compensate for that load. The Idle-up solenoid stabilizes idle speed when engine load is higher because of electrical load, power steering pump, etc.

pretty much surplus to requirements as my ac is in the bin. Thanks for the info put my mind at ease knowing no damage done
