This is the all-door trigger. 

you don't mean current/amperage, you mean voltage.  The appropriate lt.blue/white wire will show 5->12 volts when all doors are closed and 0vdc (or ground) when any of the doors are open.

what do you mean by, "All I am getting is full 'current' through every wire." Through every wire during what situations: door open/closed? Full 'current'?? You mean 12 volts?
