The alarm is super easy to install, it goes under the rear seat area. Buy the plug -in for the Busa, it simply plugs into a oem plug in the taillight area, The motion sensor sits under the black rubber band just aft of the battery and plugs into the harness, the siren or main blk box will velcro to the right(starboard) side sitting upright in the recess which seems to be made for it. The antenna will sit on top of the plastic vertical wall seperating the tool area from the steel hoop the seat prong inserts into, drill small holes along the top ridge to plastic tie the wire ( only the last section of wire is the actual antenna) get it up along the top of the plastic. DO NOT plug the connectors into the main unit be fore connecting the blue power clip onto the battery. Hope this helps.
