Boot lock help

[Telf 222 2 Cars]

With the ongoing rebuild of my car I've hit a snag with the boot lock that I can't resolve.

 

Basically I have the lock for the key, the lock mechanism and the latch in the boot floor. I also have the central locking motor and single metal rod. 

 

I cannot remember how it all goes together, how the key lock connects to the lock or if I'm missing some essential part . Does anybody have a picture of how it all fits please?

I'm still no further along with this- if someone could take a pic of the assembly in situ it would be a big help
