The connecting block near the top right in pic, was/is not connected to anything.
That said, this V6 has no remote c locking and only locks from the pass side

On the post ford R reg v6, standard remote c locking works, again the key only works in the pass side door not the drivers

Both cars have these elec blocks, if this is not for the locking system, then may be for the door lights

As sneakz has mentioned, you can tap into the interior light, I've done this in the footwell so can help if needed
Hope this helps in some way
