window switches

i'll be out parting rodeos and troopers tomorrow.. and got to thinking.. it would be REALLY nice to have an auto down function for the passenger side window too.. anyone know if it is just a different switch.. or if its new wiring too? anyone done this before? I'm hoping itll be a fairly easy conversion...

I don't know but have had the same idea for some time now. If anyone out there does know, do tell. And ETL if you get it going let me know how :)
