My engine has no spark

There are two hot wires not connected. Could they be the problem and where do they go? The engine I'm trying to run is an 86 350 from a full size chevy van. It's got compression fuel going to the carb new plugs and pretty much everything else. The distributor is older but I was told it still functions. There are two wires that I found out today are hot but I don't know what they connect to. The first one comes out of a harness that connects to the distributor cap from somewhere in the cab and the other wire runs up by the alternator where by where you plug in the f and r wire harness near the battery terminal. I'm not sure what the wires hook to.
