Woody, we did the conversion on a '90 Classic we have, and it was already done on our '93. On the '90, I fished the wire (the hard part), had a HVAC tech do the wiring. Took a $100 worth of relays, and about an hour of his time. He did something up top, under the shroud, then the rest inside the interior ac air box. We love it.
