Don't you want your rear passengers to kepp fit Mark?
Joking aside, you've asked a very big question there. I'll try and create a list of what you'll need, assuming you only have the basic front window set up.
Rear window electric regulators (left & right)
Rear door looms (L&R)
Rear window door cards including window switches (may as well get the front door cards from the donor to match)
Drivers door window switchpack (gives driver control over rear windows
Drivers door loom for 4-window operation
Any other loom not already fitted to link from drivers window switchpack to rear doors
I
think that's everything - now for the good bit!
There's a chance that the original loom has the wiring for all 4 windows to be electrically controlled in which case, you'll probably only need the window regs, rear door switches and drivers switchpack. You'll need the door cards as well of course but that would be for either option.
Easiest way of finding out what you'll need is to remove the drivers window switchpack and have a look to see if the wiring is there for two extra switches to plug onto it. Then remove the door card(s) from one or both rear doors and see if there is wiring there for the window switch in each and the motor.
That's about the only way you can be certain of what you're starting with, until you know that you won't know exactly what you need.
I think i've covered everything in the list above, apologies if not but it gives you a good starting point for checking to see what you'll need.
