this is one of the easyist things to do, it takes roughly 10 min
1)take of the dome light cover by undoing that screw
2)take out the fixture by undoing the other screw (you'll see it)
3)dissconnect the power cord thingy so you dont blow ur fuse, i did that like 3 times
4)find the power wire for the dome light, then connect the power wire from the radar detector to it, then find a ground for the other wire, the silver thing ull see works nicely, just make sure it's not the one for the dome light
5)then put it all back in reverse and voila, mount it where you like and ur done
if you have any questions just ask
