Question for the experts... I'm looking at two very factory looking punched holes. One in the firewall directly to the right of the cruise harness hole and one on the drivers A-pillar. The A-pillar hole had a plastic block-off plug I believe. Truck had manual windows so the A-pillar hole is a mystery but obviously the plug means it was a mistake or just not used for anything. The firewall hole is the big question, what was it used for? 1989 K3500 reg cab dually L19 M40 C60
