Hello fellow Kansas Stovebolter! The knobs and their use from left to right are headlights, wipers, manual choke, ignition and cigarette lighter (power port for cell phone). If the cigarette lighter was not installed it should have a black plug. If you need a factory choke cable and a delete plug for the far right hole send me a personal e-mail and I can help you out. You can also find these parts at chevyduty.com, lmctruck.com or jimcarter.com. There are many aftermarket truck suppliers that sell replacement parts for '60-'66 Chevy trucks. Best of luck with your '64.
