D13B2 - what's this wire?
Hi all,
Got myself a '92 1.3 civic last week, and all was well until it died today - oil and battery lights on, engine dead. Anyways, it happily started again so I drove home and had a look around. Couldn't see anything obviously wrong, but then I found this mystery wire that goes nowhere... Can anyone tell me what it is and if it should be connected somewhere?

Should I just be able to plug it back in?
