Installed the sequential mirror repeaters. This video was more helpful to me than the ones that say to remove the mirror. I tried removing the mirror, but gave up when it just didn't want to budge. I did have to use a couple of screwdrivers to
gently pry the clips apart; one small blade on the bottom clip and an average size one on the top. I wedged the bottom clip open with the small screwdriver and pried-up on the top clip with the other. The driver's side took me about a half hour and the passenger side about 10 minutes. I am pleased with the outcome.
