. GREAT price George! I got the chirping one before the mega price jump, and installed it in parallel with the OEM one. The OEM was relocated to the inside panel of the passenger side under hood electrical box where the RCM module rests. It is behind the heat shield mounted directly outside the RCM on that box. I have TWO sirens wail when the alarm sounds, quite annoying! I like it, and will soon take them both out and see if the batteries need replacing (can solder, can dremel, can goop). Much cheaper than ordering a part costing over a hundred bucks (and climbing). Not to mention, I like two in the circuit!
