Im installing an alarm on a 2000 Lincoln LS...I need to know how to wire the relay to `isolate` the door trigger.
Techsoft says "This wire may cause the aftermarket alarm to false when the vehicles electrical system shuts down. Use a relay to isolate it."

With a torch and a big enough hammer...it WILL friggin fit!!

Wire the relay like this: 85 door trigger from car, 86 opposite of door trigger( sorry I don't remember polarity, think the door trigger is positive), 30 ground, 87 -trigger door trigger input from alarm.
