Just a very brief post. This assumes you know how to remove the door panel, follow the wiring diagram for your kit etc. All you need is a single actuator, and wire up the green/blue to trigger the existing central locking. Based on my picture, it may look like a lot of trial and error, but someone else has tried (failed) to put remote locking in this car before, as they drilled many holes and already ran some wire.
Purple: bend this out slightly, otherwise your window will eat your actuator.
Red: this is your actuator rod, it meets up with the factory door lock rod thing
Green: this is where you put your block that joins the two rods together, using the large hole on the right to put a screw driver in and tighten up.
