another cable connection, the clamp above the arrow point holds the cable housing, the peg is where the cable end loop connects .... there's yet another cable connect setup at the left side of that pic - those are both prolly from the original installation in whatever it came from, the car had some fresh air controls, and the air input ran along the inner fender from an opening at the front next to the rad - prolly the installer tried to copy the same arrangement with that 'custom ductwork'
