In a old posting, someone mentioned that you can amplify the ground pulse to
the door lock/unlock by adding a relay. If I read this correctly, would it be the following:
#30 to door lock
#85 12volt constant
#86 from alarm
#87 ground
#87a not used

Hi roxy, if you have a negative pulse from the alarm going to #86 as you described above, that would be correct.
