I spent a few years working as both a builder and a production manager for a military aerospace subcontractor where we built electrical components, instrument panels, and wiring harnesses. I am really impressed with the data placards on the instrument housings on the back of your panel - that's looking very authentic! I wish that some of my former employees could have laid out their wire runs as neatly as you've done here, would have made life easier on my quality inspectors. Any plans to string tie the various runs together into harness forms?
