Well Im new to this forum and wanted to make my first post a useful one!
I appreciate all the info on this site, and I hope others find this mod, and appreciate its value.
I am going to tell you how I upgraded my factory antitheft system to incorporate a glass breakage sensor, and add additional led's in alternative locations. But first, my reasoning... I need a more comprehensive alarm than the one that came on my Mounty, but I cant afford $250+ right now, so I did my homework and for less than $30 I upgraded my alarm to suit my needs.
Seeing as how most suv breakins around here are "smash and grab" (or sometimes "smash and lengthy disconnect!") and the crooks know not to open the doors to get around our crappy antitheft system; I needed a way to protect my upcoming stereo system install.
I chose the glass break sensor to keep my horn alerts down to real theft attempts, and not thunder or exhausts. The sensor I used a a DEI(directed)506t, but any of them on ebay should work, as long as thier output is at least 100mA.
The sensor is a negative trigger input, so a Bosch relay was used, purchased from autozone.
The sensor is wired into the door pin circuit of the alarm at the harness in the drivers kick panel, its dark blue with a light green stripe.
The wiring goes like this - connect the (-) output of the glass break sensor to Pin 86 of a Bosch style relay. Connect Pin 85 and Pin 30 to constant power. Connect Pin 87 to the wire listed above.
Connect the 12vdc wire of the sensor directly to constant power, connect the ground of the sensor to an ignition wire, i forget what color it was. When the ignition is off it will rest at ground and provide ground to the sensor, enabling it. When started or on, sensor will not reach ground, disabling it.
As for the led's, also available in great variety online, I added a lead to the dark blue/light green wire at the left connector of the guage cluster, and grounded to the black one. This tapped into the existing antitheft light and I placed leds in each corner of the dash, as well as one center back glass.
The glass break sensor could be a shock sensor, perimiter radar, or any other negative trigger input alarm peripheral and would be tied in the exact same way.
