Install guages in place of hvac?
I would like to remove the hvac and install some guages or replace the hvac with my radio and install guages at the bottom. I have a brand new ac compressor, but never hooked the lines up. I really only use heat. Would it be possible to wire a swich to turn full heat on and off and maybe a dial to adjust blower speed? I could probably mount this on the center console somwhere. Has anyone heard of this before?
