Check List!
Equipment list and tools!
You will need:
- Pliers
- Flat head screwdriver
- Hawk Universal Remote Central Locking Upgrade Kit
- Cable ties
- Wire Connector blocks
- 10mm spanner
- 5/6mm Allen key (sorry can't remember what size it is).
- Velcro with adhesive backing
- some patience
connector blocks (i think thats their names) look like this:

You could use scotch locks instead (I did actually use them too). However the only problem i had with my installation was a scotch lock failing to splice the wire so for that reason i will in future avoid them like the plague! Use them if you like but for certainty use connector blocks! Another alternative is bullet connectors and crimps but this is pretty fiddly given the restricted space.
Some wire strippers would make your life a bit easier too but i just used my pliers.
Your hawk upgrade kit will look daunting but don't fear it's not so hard!
