It can be done, but its not easy by any means, 1- you will have to swap the h3 heater core, 2 - you will need all parts (heater core, hvac controls from h3, and wiring harnesses from both). Then you will need to cut both harnesses apart and repin it. I am in the process of finishing all this and its been a project to say the least.
