The wire colours are not correct for the simple back door lock but the wire numbers and how they relate to the plug connector are. (easy enough to see and understand whats going on)
The wire colours and wire numbers seem correct for the power rear door lock.
You can see the power rear door motor can rotate both ways to lock and unlock the boot, the negative and positive are fed from the body control module so it can rotate polarity. On the simple door lock you can see its only supplied a positive from the control module and is earthed down the other side meaning the motor/actuator can only rotate one way to unlock the boot. Manually pushing the boot door closed does the locking part so no electrical motions required.
The notification switch indicating the boot door is open or not should be straight forward enough to wire in
Can someone verify when you manually close the boot on a powered boot car the lock catches over mechanically and locks. Obviously i dont have the electrical hardware to rotate the locking motor both directions so i hope the lock mechanism works the same way roughly
I hope that makes some sense
