Thats because its the wrong unlock wire. You can only test them with the doors closed and using the key in the PassenGer door. Left hand drive cars its the drivers side / right hand drive its the left side . use the white /green yelow for unlock and blue /red for lock or opposite. they are the 2 wires that stay at 12v until the opossite is used ie: lock the door with key one wire will show 12v and it stays at 12v till its unlocked. those are your wires.if you use the other recomended wires you will have a probleme with double locking and unlocking . the dead bolts dont activate in this state.
Goodluck
