If i knew how to post a pic i would show you that way, the light unit simply "pops" into place, if you were in the car looking at the unit, insert a screwdriver about 1 inch from the left side going to the right and push the blade in, doing this you will feel pressure from the killer clip they have in there,, then you will be able to pull that end of the light unit down somewhat, then do the same to the right side too, once you have the front edge down and out, you will see how the back side is and then able to drop the unit out.
once out you will see the power wire, there are 2 wires on mine, one had a green stripe and the other a red stripe, i used the volt meter and the red side was my "hot" wire, i simply used one of those blue crimp on "in line" wire crimpers to apply the radar detector wire for power.
hope this wasnt to confusing, i will try to learn how to go about doing fotos, they sure help when teaching folks stuff.
God Bless you Folks here at the Forums.
