I am helping Don install under dash A/C and while we have the instrument panel out we decided to make it easier to put it into the car so Don added two connectors so most of the wiring stays on the panel and one connector on each side joins to the main harness. I added an oil gauge where the Chevelle name plate was, also where the clock would be if so installed. Over the years people have cut out wiring/ added wiring and it is a total mess under there. They even cut out the bulb for the charge light, I found the wires last night and will find a way to reinstall a bulb and have it behind the dash tied up of course.
