taking the gauge out is a snap(no pun intended), take the top two srcews out. then rip out the top piece. use a fllathead to pop up the end that is away from the windshield, then pull it toward the rear of the car(it a pain to get back in). a few bolts, light dimmer and rear d/f wires to get the piece around the gauge off. a few more bolts, the wiring harness and its out. i can do it in 10, 15 minutes tops
