Connectors Under Dash

You didn't tell us the year of your car. Early ones (to ~1970) used a 2 row connector on the steering column with squarish pins. Later ones (key in column?) had a long single row connector. The early ones are easy to release with a little screwdriver. I even did that in a junkyard in 1 min. Sorry, I don't have photos, but just play with it and should be obvious. There is a name for that connector, but forgot. You can't buy new ones. I recall it was a firewall connector in some GM or Ford's. The other 2 & 3 pin connectors under dash as mostly "Packard 56 terminal" type, sometimes called "GM, Mopar". You can buy most parts on ebay or auto electronics supply. Those pins are trickier to release. The female pins need a thin, flat screwdriver type thing, best with the end bent down slightly. I made a tool from a tiny hand saw from the dollar store. The male pins are squeezed longitudinally to close the long gap, and wiggle out.
