AC wiring?

[booyaballer]

I've tried checking the shop manual's wiring diagrams but i'm hitting the easy button and reaching out to the think tank!!

This module is on the backside of the dash on the passenger side with the black plug connected. I believe the wiring splits off including to the AC controls (red connector).

Is that correct?

Is it strictly for the AC?

Does it have anything to do with the heater or defrost?

Thanks!

@booyaballer that is the Key-In Buzzer module.

Yellow w/ Black tracer - One eventually goes into the Time Delay Relay the other goes into the Right Door Switch
Red - Goes to the Ignition Switch and if equipped Light Buzzer Diode
Blue with tracer - Goes to a splice that goes to Ignition Switch, Brake Warning Light, Alternator Regulator
