You should have gotten a few pages of instruction in the zip lock bag. You will need a 3/8" ratchet, 6" extension and 10mm socket (needle nose pliers where also on the list). The bezel pops up by pulling up. There is insulation/foam inside the housing, it is a pain in the rear to get out, I tore mine removing it and just taped it together and pushed it back in. There are 4 10mm bolts, remove them. Pull the metal isolator out of the bushings, gently adjust the base to get underneath to push the bushings out from the bottom side. Set all four bushings into the rubber bushings locations, drop all four bolts into place. Tighten down, replace foam, clip bezel back down and you're done.
