My Max didn't come factory with automatic climate control and I was wondering if I could buy the unit and put it in. Would it require additional wiring? Or is everything there? And how much would I pay for it?
thanks.

 

please do a search. this has been discussed PLENTY of times.
it would not be worth it. control unit itself is about $300 i think. you would need completely diffirent wiring. plus inside and outside temp sensors. all together ball park, $500+ and 10+ hours of work.
