I have no idea if this thread is appropriate here, if not I can move it.

I have a 1994 Honda civic sedan and took out the battery a few weeks ago and left it like that. I had to replace a fusible link, and I got that done with yesterday.

Came into another problem with the wiring...I don't know where one of them goes.

It's a small black 18G with blue tip wire. I already have the Positive hooked up with two other wires; one of them is a yellow 12G with a 20amp fuse in it, the other is a black 18G with a 5amp fuse in it - both of these seem to be connected to one wire end terminal which hooks up to the Positive of the battery.

Then there is the other black 18G with no fuse in which I am wondering where it goes. Obviously, not to the the negative....right? Please help, I don't know much about car's electrical, and I spent an hour online trying to hunt down stock (not souped up) pics of a civic's battery compartment to imitate it.

O My manual and Chilton's don't have any useful info.
