Fuse box question?
I recently purchased a Garmin C330 streetpilot for my 2004 6.0L. I would like to hard wire the unit into my fuse box but I am not an electrical type of person. The powersupply for my unit says ( 12/24 VDC; AGC/3AG 2 AMP fuse) where can I tap into this power on the fuse box without losing the fuse so it is protected? Also I will have to cut the cigarette lighter adapter off, which has a fuse inside of the adapter. Any suggestions you may have would be greatly appreciated. Thanks in advance!!

Look at the back of your fuse box. The large wires are the battery power (12v). These are called the buss wires. You will need to tie in to one of the buss wires and hook it to an open fuse slot in the fuse box. You will then need to hook the power wire from the Garmin unit (this wire is the line side) to the other side of the open fuse slot. You will have the buss wire on one side and the line wire on the other side then it's just a matter of installing the right fuse. Don't worry about the fuse in the lighter adapter....you won't need it with a dedicated fuse.
I have not looked at the back of the fuse box in my truck so tyhese are just guidelines. Hope they help.

My first recommendation is to use the customer access wire, its 12V switched power. It's taped to some other wires under the dashboard near the radio.
Second recommendation which is easiest is to buy a fuse tap ($20) and tap into an existing circuit.

To find the customer access wire remove the panel under the steering wheel and on the right side there are about 5 wires bundled together, the one with end that is shrink tubed is the wire. The fuse is labeled customer access and has a 10 amp fuse that you can change to a lower value. On my truck the wire was purple with a pink strip. The wire is hot only when the ignition is on.

I connected my Magellan Roadmate using a mini fusetap connected to upfitter #1 fuse (I do not have the upfitter switches). Worked great.

Also noted are the customer "pass through" circuits. There are 4 wires that travel from inside to the outside and do nothing (circuits 1353, 1487, 1795 and 1501). I used them to control the lights I added to the truck.

Here is another fuse box question and I hope I can ask it on this thread --
Do I have to disconnect the batteries on my 6.0L before changing out the fuse to the Power Point and putting in a fuse w/more amps?
Thanks in advance! --

Technically no, you should be able to remove a fuse from a live circuit, the power point is an always live circuit. Having said that I'm sure there's people out there that would try to remove a fuse with a screwdriver or something and still hurt themselves.
Make sure nothing is plugged in the powerpoint, the surge from replacing the fuse could blow it right away.
With my 1968 Mercury I remove the battery whenever dealing with electrical, since it's so easy might as well be safe. With new cars disconnecting the battery is such a pain, you lose your clock time, the computer components all reset, etc, it's noth worth it.
