Not sure if anyone is interested but I just hardwired the radar detector in my 09 Tacoma. I used the wires going to the rear view mirror. The green is the positive and the white/black is the ground. It only took a few minutes and it works perfect. It only comes on when the key is in the "on" position.
To get the clock assembly down there is only one screw in the sunglass holder compartment and then just pull down on the front of the assembly to release the two clips. It couldn't be easier.
