I think the problem you are having is that you are trying to use too many wires. There are many types of central locking system which need to be connected to the alarm in different ways. Hence the alarm will normally provide more wires than you need.

You either need two or three wires. One will go to the locking ground, one will go the the unlocking ground and one might go to earth (alternatively the alarms own earth may be used. You shouldn't need to cut any of the locking wires that are already in the car, - you just splice into them.

Your car employers a negative switched system so you need to use the diagram that applies to this system. I can't make out which diagram it is from the pictures you've put up because they are too small.

If the locking is stuck in a lock-unlock cycle this is almost certainly because lock and unlock are both earthed at the same time which shouldn't happen.
