central locking UK spec L200

help!

can anyone help me with the wiring on a 2004 uk spec Mistibushi L200 Warrior?

I am trying to wire in a keyless entry system.  the vehicle already has central locking, but no remote.  i have the kit, just need to wire it in.  in the drivers door, i have 4 wires:

blue with red strip,  blue with black stripe,  black with red stripe,  black (with black stripe?)

any ideas on what wire does what?

you will need to add a 2 wire central door locking motor to the drivers side to lock the drivers door from your alarm this will then lock the other doors .
