This will be slightly different since it's from my 2015 TC wiring book instead of the 2016 provided by Don Ridley earlier. But here is a diagram of the equivalent connector in my 2015. Also, if you look closely at the connector, there is usually some numerical marking of the pins so you may be able to match the earlier schematic that way.
Better image.
After closer review the door switch provides a GND connection to activate the relay that opens the door. It does not look like you can separately add a GND to the relay that would open the door regardless of the lock/unlock status.
