We all know he was just trying to help....but.....he really should've left it alone.
When I bought my '66 Shelby GT350 the instrument panel asn't original. It was just a piece of black painted aluminum with Stewart-Warner gauges installed, most of which weren't working. I pulled the panel to take a look and screamed. The previous owner didn't bother to pull the connectors he just cut all the wires going to the original gauges. I spend several hours tracing and labeling wires.
BTW, nice job. Looks neat and orderly.
