Corsica -90 where does a cable go?
 

I was out changing the headlight switch on my dads Corsica -90 when my neighbour came by and accidentally janked a cable out. And I need to figure out where it goes...

My guess is that it goes to the fuse box, or somewhere in the vincinity (as it seems to originate from somewhere around there). The easy thing here is that it is labeled,
'KA 901
1 AMP'
but I don't have the manual to figure out where it goes, could anyone give me a hint or hopefully even the answer to where it goes?

On the end of the cable there is a flat contact (the one that was janked out) labeled "15" in case that helps at all...

Thanks a lot!
