I am removing all traces of A/C from my 84 SC. I got a non/ac heater box blower and squirrel cage, and am looking for a control panel. My question is, will everything plug in without switching harnesses? What about the vaccuum lines? Thanks

 

you can use your original control head to work a non-A/C unit, if you want to save yourself some time. I took out all my A/C stuff, but left the factory HVAC unit in the dash. Works fine now.

 

It's probably not worth the trouble changing the head. Non A/C heaters are cable actuated, not vacuum actuated.
