91 Z28 AC connector

Hi. I bought my Z28 with no engine and am in the middle of an LS swap. I can't get the blower motor working for the heat/ac. Does anyone know where this plug goes? It has 4 wires.

That's C105. It's where the HVAC harness gets power from the engine harness, and the compressor gets it's inputs from the rest of the car.

Ah hah! You're a lifesaver. Thus was driving me nuts. Looked at the diagrams and couldn't find anything. The PO started the swap and dissasembled most of the wiring.
