have a 1990 sunbird corsica
with a 5.0 litre engine cobra omc inboard/outdrive

just noticed while hooking up my battery cables
there was one wire to put onto battery
( it is a brown wire than the wire turns into orange and there is a fuse with it)
what could this wire be for and does it go on the positive or negative on the battery
thanks
