The alarm that I recently purchased has an output for an optional horn relay. I have the relay, but an unsure how to wire it to the car and to the alarm. The output from the alarm is negative, and the horn is listed as negative too. The car is a 95 integra. Thanks for the help.

1 SPDT Relay:

PIN 87 = Ground
PIN 30 = GRAY Horn wire
PIN 85 = Negative Output from Alarm
PIN 86 = Constant 12 volt ( + )
