Okay I have actually just completed this today!
Ready here ya go:
1. Go to radio shack and get a 12v Cigarette Lighter Power source. They are only 7.99 plus tax here In Ga.
2. Go and find a spot under the dash taht you can get to a little easy for it to mount.
I don't know how your dash but on the 99+ I put mine in teh shifter console (manual tranny). Find a good switched 12v power source (power only when key is on) and a good ground. That is all.
