fuse box wiring

Can anybody tell me how to hook up the acc/ignition wire to my fuse box?Chris Rocks

You need to more specific in both your vehicle and what current you need. sparky

It is a 2003 malibu.  I am hooking up my stereo, and in the manual it says that everything will work, but I just need to hook up the acc/ign wire to the fuse box because for my car, that is how you have to do it.Chris Rocks

do you need it for the remote on an amp?99 Blazer LT.   Yellow Top. Big 3. Infinity Kappa Speakers All Around. Jensen CD/DVD flip out. 2 Infinity Kappa Perfect 12DVQs powered by a Alpine PDX600.1 (in one custom box, building a FG box)

You can use a module that retains the factory chimes and other functions that may be lost when you remove the factory radio.  This will also supply an accessory lead for the radio, but these units aren't cheap- ask your stereo shop.  I don't like fuse taps, because they can actually damage the connectors inside the fuse block.  If you're not using a module, I'd tap the thick brown wire at the ignition harness and fuse your wire.  Test the wires with a multimeter.My ex once told me I have a perfect face for radio.
