This Thing Is Driving Me Crazy

Dodge Dakota 2002....Crimestopper CS2000The door negative trigger was wired to the dome light circuit which has a fade off delay, this caused the alarm to chirp 3 times telling me there is a zone fault and also the delay was preventing the doors from locking because the cpu thought the door was open, other than that everything worked I found in the drivers kick panel a tan wire for the passsenger door trigger and a tan/red wire for the passenger door, these triggers are actually for the door ajar light they are - when doors are open and read nothing when doors are closed, thought I was on to something, used the diode method to wire the two to the alarm. now 30 sec after being armed the alarm goes off. Why ??????

I used the diodes
