Problem with 2003 Focus alarm install

I Installed a Prestige APS-600 on a Ford Focus, however, I cannot get the door trigger nor the trunk trigger to work.  I tapped the door trigger wire to the black / blue wire under driver kick as mentioned in the wiring diagram, and under another black / blue wire for trunk at the same location.  The door trigger wire shows ground when the door is opened, but only about 0.5 V when doors are closed instead of the usual 12V.  Therefore, the alarm thinks that the door is opened at all times.  as for the other black / blue wire, nothing seems to change when i open / close the door and trunk.  Any help is appreciated!  Thanks!
