I had a look this afternoon.
I took off the panel completely, but, of course, you will not be able to do this.
Remove as many screws as possible, and the two black plugs, one on each bottom corner.
This should allow you to push out the bottom enough to look inside.
I took the red plug out of the electric lock, which is up near the window, the plug is on the left hand side, near the middle.
I couldnt find out which pin to apply 12v to, so I took pot luck, and it pinged open.
Today I noticed that on the cable harness coming from the left, there was a plug. This one had at least one cable going up to the lock.
What I suggest is, if you have this on yours, that you apply a voltage to either, in turn, and see what happens.
I have photos, so let me know if you need to see them. (Not sure how I will do that.)
