Retro-fit Power Windows/Central Locking

JameCour

Hi Iam fitting Central locking and Power windows to an old VW Camper ('79 Bay).
I already have the window motors (BMW) and door actuators (Swiss) which i know will work.

What i need is a 'Remote key fob' type controller to make it all work but Iam having trouble sourcing the parts i will need.

I have looked at various fleabay kits but can't find anything that has similar VW Golf functions
I.e.

1. Press the Lock button once: Lock all Doors
2. Hold the Lock button down: Close the Windows (finger off, window stops. Hold again window starts again).
3. Press the unlock button once: Unlock all Doors
4. Hold the unlock button down: Open the Windows (finger off, window stops. Hold again window starts again).

Does anyone know if a kit like this exists? Or has done something similar?
Thanks

Note:
Lock/Unlock doors is for 3 doors
Power windows is on 2 doors

Most likely discontinued now but I installed a Falcon Evo3 pager alarm system to my mk1 mr2. This allowed lock/unlock doors, open/close windows, boot pop, remote start.
