The siren is mounted under passenger seat on top of ECM. I don't know about other years, but the 2012 has clips for the siren to be snapped into place. The yellow dashes indicate the antenna wire. The white dashes highlight the velcro strip that comes with package. I cut the width in half and attached it to the frame. The antenna wire (the narrow part of it) is in between the velcro to keep it from touching metal. Took less than 10 minutes to install. I did not remove the maxi fuse as recommended in the instructions, just made sure the ignition switch was off. On the 2012, the power cable/connector is already located near the ECM. On earlier models (not sure which) the cable may have to be routed from the fuel tank area (according to the instructions).
