I purchased a similar kit off ebay but it never had any actuators.
45mins work yesterday and I got it working, although I had to lubricate my locking mechanism because it would unlock and try to lock but due to the stiff mechanism it wouldn't so a bit of wd40 and job done.
The system I purchased was this one
UKSH CAR DOOR REMOTE CENTRAL LOCKING KEYLESS ENTRY LOCK on eBay (end time 20-Apr-11 09:29:22 BST)
There's alot of wires in the kit however I fitted it like this.
1. Red and Black to a positive and negative feed I already had routed for a solar charger which i find it a waste of time so i used those to power the control unit.
2. White/black connected to the Orange lead in the drivers door, had to change the 10a fuse for a 20a as it kept blowing
3. White lead connected to the Pink lead in the drivers door
4. Yellow and Yellow/Black from the control unit both connected to the positive feed
Then just needed to lubricate the door lock mechanism but others may not have to do this.
I do have 2 brown wires from the control unit that connect to the indicators but I didn't bother connecting these cause I couldn't be arsed lol
