Fast question with pic

Any ideas what connector this is? i found it disconnected when removing my plastics for painting. Should i be worried or should it be like that?

Sorry if this was noob question, just got worried. Cheers.

it,s a spare don.t worry

Thanks mate for fast reply.

what he said.... just above it there should be a valve with a 1/4 inch hose and a quick disconnect attached to it. Its mounted on the front brake lever side of the bike on the frame.... its on the front top corner where two frame tubes come together.

Plug that ish back in if you have it.... no use letting it hang around I guess.]

Did it give you an FI light at all?
