I have kind of a wiered situation. I was recently given a 1962 mercedes 190. I have decided to make the car a showoff peice for carputer integration and to show that it doesnt have to be a fairly new car to be well integrated. But what I was wondering is based on the expieriences of you guys here what is the easiet A/C system to control through software? I know there are a ton of them that work but I would prefer to skip the phidgets route and get a controllor for a system such as a cadillac or a buick or whatever that is digitally controlled and just emulate the pinouts that way. So have you guys dealt with any system that were fairly straight forward to integrate?
