Hardwiring Radar Detector
I don't know about you, but having those annoying radar detector cords hanging down from your windshield just makes your car look tacky.  I'm the kind of guy that likes tons of electronic toys in my car, but no wires showing.  To accomplish this task with my new Cobra ESD-6500 detector, I acquired a hardwiring kit (from Wal-Mart / Best Buy for about $12.00).  The kit is not necessary, but it makes the job easier.  Basically the kit comes with a straight piece of wire with an adapter plug for your radar on one end, and an inline fuse on the other.  All you have to do is choose the proper plug for your detector, and route the wires down to your fuse box.

    Now, getting the wires down to the fuse box is a bit of a challenge.  It seems our friends at Pontiac didn't want those plastic moldings inside our car to ever come off.  Well, they did a good job of securing them.  After discovering that the clips will break off if you try to remove the moldings, I had to pay a little visit to my local dealership.  After playing stupid with the service guys, I managed to get a replacement piece for free.  But before the piece was installed, I completed routing the wires for the detector.

    I chose to mount my detector just above my rear view mirror.  This way it is out of the way and out of site for potential thieves.  To supply power to the unit, I first started down at the fuse box and began tucking the wires up behind the drivers side window molding.  I recommend that you do not try and remove the drivers side "A" pillar molding.  Once I made it to the top of the window, I tucked the remainder of the wire above the headliner and left enough wire dangling to connect the radar detector.

    After successfully concealing all of the wires for the detector, now came the job of supplying power to the unit.   Basically all you need is a 12 volt power supply and a ground.  I chose to ground my detector to a bolt that connects your front fender to the chassis.  The bolt just happens to be located next to your fuse box (how convenient?).  After securing a solid ground, I then removed the 10 amp fuse for the radio.  I then stripped the wire sheathe and inserted it into the fuse block.  All that was left was to reinsert the radio fuse and replace the fuse box cover.

I chose the 10 amp radio fuse because this circuit only gets power when the key is in the "ON" or "ACCESSORIES" position.  That is really the only time you should need your radar, duh!!  So now when I turn on my car, my radar detector automatically turns itself on.  And when I shut off the car, the detector shuts off as well.  No more drained batteries.
