Freelander 1 Tailgate window and door electrics help.

Hi everyone, looking for some help with the electrics in my rear tailgate please.
I have ordered a new window motor and regulator to try and get it all running, however the rear lock won't lock even if I use the key, the barrel just won't turn to the left. The rear wiper doesn't work and neither does the washer jet, however the brake light does so must have some electric going to the rear haha.
Has anyone got pictures of how it should be wired up so I have something to go off .
I'm not sure if stuff has been bodged before and what's original and what isn't, the window has been bolted up so think it's had issues for some time. I have attached some pictures.
Thanks for any help.

The key doesnt open the tailgate only via the fob key or by the driver door lock with the key itself. The tailgate window when closed should raise to seal and activate lock on the tailgate lock. There an actuator that triggers the locking mechanism and is active when all door lock are open from drivers door key or from fob or by the console. The key itself can raise the window and the fobkey near the tailgate window lower it. If the actuator is knackered that your issue sometime the lever washer comes loose and the mechanism fails to engage.
Hope this helps

If the CCU doesn't think the rear window is up, it inhibits the wiper, washer and heated window operation. Once you get the window operation sorted, everything else should work.
The rear window can be lowered from the fob, by holding the unlock button. The window is then closed by turning the rear door key until the window is fully up. If the key doesn't turn, then it's probably had a second hand handle fitted, where the key barrel hasn't been swapped over.
