hah! I'm sure you're right. Forgot all about the cab. Think I'm going to mount some kind of a heater inside the cab, under the passenger-side of the dash, sort of like the A3's, instead of in the engine compartment like the A2's. Also going to try to maintain a sealed firewall, instead of passing things through gaping holes. So will punch through wherever I end up needing to, and will use grommets and/or bulkhead connectors.
