Default 924 Heater Hookup


How do I connect the heater switch? Are my wires connected properly?

Right now the heater only works on high. I think it may be connected directly with the square connectors in the back that is wrapped in green. I am trying to get the switch to work, so I can adjust to different speeds. The orange wire is coming from the driver side, so I would think from the fuse box. Then this brown wire is joined together, but I was able to plug it in. I think it's the wire that sends the signal to the blower to slow down.
I think I got the correct wires for the heater switch. Not sure if I have the orange and brown connected to the proper connector.

The wire going to the square connector is black and red.

I have no idea what these ones are for. Has a skinny and wide connector and a light.

So it looks like the black and red wire is the power wire for the blower motor. Right now it's connected directly to the blower, bi-passing the switch. The blower motor wire is blue. I was hoping I could disconnect the square connector and then connect the two wires to the switch. I can disconnect the black/red wire, but the blue one is hard wired to the square connector. I don't want to disconnect the blue wire before I know if the 2 wires should be connected to the switch, and I'm not sure which where goes where. I am not sure if the wiring is 924 original. I think there are some 944 parts in my car.
I need help wiring the heater switch. Would the black/red wire go on 1, and then blue on 2?
