1993 saturn sl2 alarm, door locks

ok im having another issue with installing my car alarm. I found the white door trigger wire behind the fuse panel, when i hooked up the blue - wire from the alarm for the door trigger, only when i open the rear doors will the alarm sound. I get nothing when i open the front doors. When i tested the white wire with a test light this is what i get:   This is from the front driver side door.... When test light hits wire i get nothing. when i pust the door pin on the drivers front side the test light lights up and when the push pin is release light goes out, so im sure i have the correct wire for the door trigger i just get nothing out of the front doors. am i doing something wrong?
