04 Jeep Liberty, False Door Trigger

I just installed a Code Alarm Pc4200 in a 04 liberty and had some problems with the door trigger.  Directechs said tan for drivers and tan/white for passenger door.  the liberty has 4 doors.  I look in the blue plug and found tan, tan / YELLOW, tan/red, tan/orange.  all these wires tested as negative triggers for each door.  I isolated all the triggers with diodes and when i armed the jeep the alarm went off about 20 seconds later.  after trying to figure it out I just wire it to the domelight and it works fine except the delay but no big deal.  just wonding if anyone has had this issue or know why this is happening.

Did you use 1 amp diodes with the band side facing oem wires?

Your domelight delay is probably setting off your alarm.  Try connecting the domelight supervision to your door triggerDo it right the first time
