    Default Fuse Box Diagram

    I didn't get an owners manual with my car, so I was looking for a fuse box diagram. Specifically, I want to know what circuits are not used, and when they have power (always on, on when the key is at run, ect...). I've got afew accessories I want to wire up, and I would like to make it as clean as possible.

    Don't have next to me right now, but I recall looking at it and then noticing that half of it didn't match against what my fuse box has. My fuse box is labeled (says things like "F/P", "ECM", "B/U Light", etc), I just go by what it says. Is yours labeled?

    Crap, I wanted to use fuse taps on the un-used sockets on the fuse box.

    The "unused" ones I have don't have the connectors inside of them to attach a fuse. I think there's one on the top left corner labelled as "Batt" though that might have had a working connector, but not for a normal fuse. What exactly is a fuse tap...that "Batt" port may be for that...

    A fuse tap is typically a copper strip of metal that clips over one of the terminals of a fuse and sticks out past the fuse. Once connected, you can connect a female spade terminal connector to it. This allows you to "tap" power from the fuse to power other accessories.

    If you install them properly (downstream of your power source), you do not have to use an inline fuse as the power travels through the fuse to the accessory.

    Judging by your description, you might be able to use that unused Batt port, if it exists on your end. I know it does on mine.

    I popped the fuse cover today. I found one socket labeled "Batt" and another labeled "Ign". I'm assuming "Batt" is hot off the battery, and "Ign" is hot when the ignition is on.

    I was in a hurry and didn't look at the connections that closely. The next step will be to wire up to it. Once I have wires off of it, I can fuse it for whatever amperage I want and mount a power distribution box under the dash. The boxes are less than $10 at the parts stores and usually have 4 or 6 fuseable ports on them. At that point, I can wire up all the accessories I could want.

    I plan on mounting a 400 watt AC inverter under the dash so I can run small AC devices (laptop).
