I just discovered that apparently the Autopage 850 doesn't actually give warning chirps. It tells the transmitter, but the car itself doesn't chirp, which is more important to me than the full alarm. Is there any way I can 'create' warning chirps through another input or relays? I have a dual shock sensor and a dual proximity sensor. Thanks!

86 & 87 = Fused +12 volts

85 = Negative Pre-warn output from sensor, with a one (1) ampere diode placed in series. Cathode / band side toward sensor.

30 = Positive input to siren

87a = Positive output from alarm system.

Knowledge is power. But only if you apply that knowledge in a positive way, which promotes positive results in others.
