it is not a direct swap. unless you have the wiring diagrams, and are a wiring CHAMP, i would advise against it. and i mean the diagrams for both cars, and i have had no luck finding the ss-iii diagram here.

it would be a massive rewire its been brought up before and im sure its completely different on the aircon / econ
if you do a search there have been a couple threads on what you would have to do to get it to work. there apparently are tons of sensors and things that would need to be installed. a big PITA and not really worth it IMO. if your car came stock with it then it's a nice perk but if not i wouldn't worry too much about it.
Call me a traitor! See if I care. ;)
