1975 Dodge Truck Choke not working on carb

It's a holley 2280 2 barrel on a 1969 318 industrial in a 1975 dodge w100. I rebuilt it because the truck couldn't idle at all, and it helped the idle. The choke still doesn't work and there are some wires that dont go anywhere. There is a wire coming off the idle screw that doesn't go anywhere, is that a ground or? There's a red thing (in pic) that looks like it should be connected to something. Finally, I cant find where the choke thermostat should be on the engine, did that engine not have that? There are some wires that aren't connected to anything right by the carb as well. Basically whats right annd whats wrong. Sorry about the pic quality.
