Finally got around to it today. 
Here's the reverse camera:
For those that are having problems with the reverse camera I tapped in at the connector on the passenger side frame rail. Green/White for (+) and black for (-):
The door lock actuator is screwed in directly to the tailgate skin:
I drilled the hole for the lock rod at pretty much exactly the "peak" of the "hump" in the lock cam:
As it's already been pointed out, the clip for the cam can be tricky and fly away on you, so be careful.
