Electric windows - full closure/opening???

[miniblob]

Right, just wondering if this is something that can be easily set up??

Would love to be able to operate all 4 electric windows up/down together, from one button!!
(Still have the button on the dash from when the cab roof used to be electric, so would ideally use that!!)

Is it something that could be wired up fairly easily??
Or are alarms with full closure using some kind of ecu to operate them all???
(I don't have full closure at the mo, but do have a sigma alarm, if that's of any use!!)

Any ideas/advice appreciated!!

Was an option from new!
Use the search function and you should be able to find a post by me where I describe how to make a simple mod. to the window wiring so that they do all operate at the same time from a fifth switch. The problem that arises is that the power feed wiring isn't really heavy enough to work four window motors at once.
