OK after reading the linked thread, and looking at your pictures, I'd say:
The Blue and Red wires at the bottom right of your photo are the timer's own power supply, and may be marked as 1 and 2 as per your diagram.
Leave these alone.
The 2 white boxes on the Left and Right of the timer unit are the relays, which switch things on and off.
On the top left, the Purple and White wires need linked.
These will we either 3&4, or 5&6, again, per your diagram.
On the top right, the 2 reds need linking.
These will be the other pair, 3&4 or 5&6, whichever the other pair wasn't.
If there's numbering on the PCB which contradicts this, then don't proceed.
After pulling the crimp connectors from the timer module, you'll probably find the crimps on the wires are the wrong sex to directly connect together; you'll need to chop one.
I'd be inclined to leave the insulated one alone, and chop the other.
Your crimp set looks fine, you'll probably need the blue ones.
Strip the insulation off the chopped wire as necessary by inspection ( the wire should just poke through the crimp, and the insulation on the wire should not be pushed into the crimping area ).
The crimping area should be filled with bare wire only, twisted nice and tight.
Place the empty crimp in the tool, in the correctly-coloured slot, lined up so the tool is pinching on the business-part of the crimp.
Ratchet the tool closed gently, so it's just gripping the crimp.
Insert the wire to the correct depth, and crimp it tightly.
