battery wire on the fusebox?

[compression]

Where does this wire lead to ? It has 1 large connector at the end, comes from the fusebox and is really long

It is connected to the fuse named " battery "

it kinda looks like its for your Air condition system going to fuse #9 20 Amp but the picture is blurry I cant really look at the connector that well

Possibly air bag, as they use yellow connectors.

believe that plugs into the area around the fuse box inside the car under the drivers side dash. does it run the length of the entire harness?

Not sure on the 1G but my 2G has a simlar connector that has a similar looking connector and it plugs into the interior fuse box.
