I HAVE A 97 FORD CROWN VICORIA and was wanting to put a relay set up to blow the car horn when the alam goes off can anyone help me correct my mistake on this circuit or just give me a better one to use.

Connect your car horn to your car alarm

Parts: 1. diode pick it up at Radio shack 2.normally close relays(just the standard one like you used for the remote start).

Step 1. Connect the positive of the diode to the positive wire of the siren.

Step 2. Tap the orange alarm wire, which is then connected to pin 85 of 1st relay, pin 86 of the relay is connected to the negative of the diode. Pin 30 is connected with a constant 12 volt, pin 87 is connected to pin 86 of the 2nd relay.

Step 3. Locate the BLACK/ white dome-light output of the alarm and connect it to pin 85 of the 2nd relay.

Step 4. Pin 30 of the 2nd relay is connected to a constant 12 volt and pin 87 is connected to the positive of the car horn. Only when the alarm is triggered will the car horn honk
