Webasto Aux heater

[71camaro]

Hello all,

As I'm sure you all realize, I'm doing quite a bit to my car right now, alcantara, air suspension, rear fridge, automated boot lid, comfort turns, possibly a solar roof, etc., etc. Anyway, I'm thinking about adding the parking heater option to my car as well using some parts available from Germany. What I know I need are the heater, the door switch, and some hoses. What else will I need to accomplish this? Is there a control module or relay system? I'm awaiting arrival of a Bentley Manual as we speak, but even so I'm not sure the diagrams for this are featured in it. Any advice or insight is appreciated.
