I put the switch for my undercar LED's in the center console. The two red buttons on the bottom row. One is the Aooga Horn button and the one on the right is a lighted toggle switch for the LED's. It lights up when the undercar lights are ON. The computer that controls the lights is that silver thing under the lights in the cubby hole.
OldCoach,
Before my LED's I had
PURPLE neon tubes. Here's a picture how I installed them along the side. Actually, the LED strips are attached the same way using screws thru the double flange. The front and rear just went into anything I could put screws into. The mounting points should be adjustable so you can find places to screw them in. The picture was for someone who wanted to know how I put the Lake Pipes on.
