Two requests: parts and information

Parts

I have an '87 build highline and I'm in need of a new switch to operate the front passenger window (fine on the down, but doesn't work on the up) I understand they changed the connection in 86, which is a b*gger. Anyone have one kicking around?

Information

In addition to that, the controls for my electric seats are on the panel behind the handbrake. If I bought a couple of new front seats with the controls on the seats themselves, would I just need to hook up a 12v supply to the 'new' seats or would I have to do some major rewiring?

Thanks for any thoughts.
