Satellite Radio, 2003 Trailblazer

I am fixing to install a Sirius Satellite Radio in a 2003 Trailblazer.  I have bought the Streamer Replay Radio which is similar to the Sportster model.  Do you have any suggestions on the install?  I don't want to use the power adapter they supplied but go directly to the fuse panel.  I know a little about electronics but not so much about the proper ways to get into a fuse panel on a car. 

Any help would be much appreciated.

Thanks,

Look at the specs or on the power port on the unit itself.  If it says 6v, then you should use the cigarette adapter that comes with it.  It converts your car's power to the power it needs.  Just buy a cigarette lighter outlet, and wire that to switched power.  Set your meter to ohms and measure from the outside rim of the plug to one of the wires- when you get a reading of nearly 0 ohms, that wire goes to ground.  Connect the other wire to the accessory wire in your vehicle (thick brown under the dash) with an inline fuse.  Test all wires with a meter first.

If your unit runs on 12 volts, you can just cut off the end and wire it direct.  Be sure to use a fuse.
