Wires in doors

[1WAZZA]

While replacing F speakers in my 98 VT I noticed two wires with connector close to the latch end of both doors. They are between the plastic liner and the panel. One wire is white with blue, the other orange with black. I checked for power with key on, lights on, door open and got nothing.
Just wondering what they could be for?
