My alarm is falsing every half hour or so. It either shows that a door is open or the trunk. It is the two way Vadar alarm. I have put diodes on both door trigers and on the trunk trigger as well. Anyone know why its doing so and what I can do to fix it.

You will need to use a relay as well as diodes to isolate the trigger wires from each other.

you can try this too....
***Dome Light:Ford's G.E.M. Will Drop A Low Signal Across The Dome Light And In Most Cases Cause A False Trigger. To Eliminate This Cut the Door Pin Trigger Wires At The G.E.M. And Insert A One-Amp Diode With Band Side Faceing Doors.Make Your Isolated Connection On The Door Pin Side. The GEM (Generic Electronic Module) is to the left of the radio

I have already installed diodes on both door trigers and on the trunk trigger. When the alarm goes off it shows as if the trunk was open, but it is not. I asummed that the diodes are ok since they were new but i am going to check just to make shure. IF ANYONE HAS ANY SUGGESTIONS PLEASE LET ME KNOW THANKS

What input are you connecting the trunk pin to( door or instant negative trigger)? Also as far as diode isolating the triggers, you need two diodes per trigger, one inline with the factory wire isolating the switch from the computer and one isolating the triggers from each other to the alarm.

The alarm i got has an input for the two door triggers and another for trunk/hood. Just a stupid question but why would you need to isolate the two door trigers from each other?

Isolating the triggers is more for the vehicle rather then the alarm. Some bcm/gem's do different things when the drivers door is open as opposed to the passenger doors being open. In your case it might be easier to move the door trigger to a the BLACK/ white(+) at the gem module and see if the alarm stops falsing. As for the trunk being a sensor that would false, you should check the latch pin, I have seen one in a focus that went bad and ended up costing a ton of money because the dealership couldn't figure out why the battery was constantly going dead, this would cause the gem to remain on and had a constant draw on the battery(had 2000 miles on it and the customer had it for 2 years, I know a little off of topic but still relevant)

Newer ford vehicles power down the door locking system after about 45 mins of inactivity. This causes a pulse on the door pins. This subject is covered elsewhere in this forum.
