AC Control bulb socket question

[Thealien]

I deleted the other thread because I couldn't even spell AC correctly.

I have been waiting about six months for an M & H under dash wiring harness. The AC harness only has one bulb socket for the AC controller. Does the other bulb socket come from the under dash harness or is that another separate small harness?

I recently dealt with this in my K20. Here’s a link to what I included in my build thread on it. My factory harness had the passenger side hvac bulb socket wrapped up and routed with the blower switch harness. The driver side came out of the main under dash harness right about where the wiper switch is. They both get power from the grey wire in the instrument cluster plug. I couldn’t get power to the passenger side bulb socket to save my life. There is a factory splice somewhere in the grey wire but rather than unwrap the harness I just tied it into the grey wire in a different more easy to access place. Everything works perfect now.

From what I recall, the heat only control panel only has one bulb, the AC panel has two bulbs.
