Hello, I recently installed an LCD pager alarm system in my 2001 expedition. I used the DEI wiring diagram and everything works fine(remote start, etc.) with one exception. My door trigger is very inconsistent. Sometimes it works, sometimes it doesn't. From time to time, it would give me false alarms stating that my doors have been opened even though they are not. Does anybody know the best wire to use for the door trigger? Thanks, John

Which wire did you end up using? The vehicle has a GEM system that shuts down and can cause false alarms if you used the improper wire or did not diode/relay isolate the wire from the truck.

Hi Jeff, I used the light blue wire according to the wiring diagram. It's located by the foot panel, all the way up. It's the 2nd wiring harness of the keyless entry. I didn'tuse a diode/relay. I just connected it directly. I didn't know about using a diode or relay. This is the only vehicle that's giving me a false alarm on the door trigger. All the other vehicles I've done have been running perfect. John

I am having the same problem with my 2003 f-150. I tapped off the black with yellow for the driver side to a diode and ran a wire from the black with purple on the passanger side to the diode and tied both to the negative trigger input. My truck after about an hour or two the alarm trips with a door intrusion. Any ideas to fix thes false alarms would be appreciated. The alarm i'm using is a Viper 791xv. Kevin

Questions on that Diagram. Are 86 and 85 connected together? and 87A and 30 connected together? Thanks, John

Use the orange and light green at the light switch and that wire will catch all doors without falsing

That's how I had it wired originally and it worked fine on regular alarms but not for the LCD paging alarm. I used the diagram given by jeff it worked perfectly. No more false alarms. Thanks for all the input. This site is AWESOME. John
