It’s a system from Ford that they market very poorly. The problem is finding a dealer that knows anything about them because the SIM in the cell module needs to be activated. Then you sign up for an account and download the app.
http://www.fordremoteaccess.com/en/ You need 2 parts to make it work, the perimeter alarm module that plugs inline with the OBDII connector, and the RMU module that plugs into the alarm module. The part numbers are
DL3Z-19A361-A (VEHICLE SECURITY SYSTEM- FORD PERIMETER PLUS MODULE)
DL3Z-19A390-B (REMOTE MESSAGING UNIT).
They are getting harder to find since Ford has a new system coming out that includes vehicle tracking and ability to monitor fuel levels, etc remotely, but the service is much more expensive. My system costs $49 Canadian a year for the service, which is about 38 bucks now. The new system is $16.99 a month + $150 activation and you can hardly find them anywhere. You can still find the old system on eBay. Don’t worry about if it says it’s for another car. It’s the part numbers that matter.
Installation takes 20 minutes. Just pop the knee panel under the steering wheel off after removing 2 screws, unscrew the OBD port, plug in the T harness, screw the new OBD port back, and mount the alarm and rmu module. I used cable ties to mount the alarm and Velcro to mount the RMU.
If you want this, hurry. The parts are drying up and I don’t think they’re gonna make this system anymore.
