Need help with finding the connection

[rusted85]

Just bought a 1985 K5, all stock w/305 auto. The carburator has a electrical connection on the top forward area with 2 wires coming out of it. One wire is laying there not hooked up. There is a plug on the end of this wire but I can't find where it connects. Could someone help me out? Thank you

I will look when I get home tonight.

This carb does not have a connector on the drivers side front, correct?

If not, that plug should go to the thermostat neck.

Someone else was just dealing with that on here, looking for the temp switch.

I bought a thermal switch today. The new switch has 2 metal spades sticking out of the top. Is there to be a second wire plugging into the switch? If so where would it come from? I'm not sure as to what this does with the carburator but I hope it improves my mileage. Correct Dyeager535 there is no other electrical connection on the carb.. Thank you for your help.

It has something to do with fuel enrichment (pump shot) under cold engine operating conditions. I don't believe it does anything once the engine warms up.

I have no experience in how they were actually wired, but it was probably as simple as 12V from the engine wiring harness into the connector at the carb, and the other wire directly to the switch, which grounds when hot or cold, depending on how the switch is setup.
