BA6 heater booster  wiring
Here is the Bentley chapter on BA6.Most folks have it already.Some dont.Better download soon , as Yahoo will delete some of these pictures as I make new alblms.Aircooled is very similar to watercooled.Only a couple of check valves added and  updates of components.Bentley has other wiring diagrams for Canadian BA6 units and watercooled units.I only give the aircooled diagram.I will take pictures of each component and it's connection on the wiring harness, pictured.
