Looks like a hard job to retrofit this feature. Hats off to you for all the documentation, which I'm sure will be useful to others who are considering or decide to make the same upgrade. Makes me thankful my box came with it. (Wife and I love to use it now that we've just figured it out too, by the way. With the memory adjust feature, the only thing we need to manually adjust to drive the car after the other one of us drove last is the interior rear-view mirror.) I still wouldn't mind having the electric heaters, though.
