Need help identifying wires/connections
Disclaimer: this car was in a front end collision with the previous owner. I’m putting everything back together. See below for the connectors/harness. It’s all on the passenger side. I have nothing on the driver side.

Pic 4
Better view of the one without a connector in pic 4: This is for the connector for the turn signals and parking lights harness. I have a connector now. Are the brown wires interchangeable?

1 - could actually be one of several possible vacuum lines which terminated near the ecu. AIR system has one. HVAC controls. Or the main vac source line itself from the rear of the intake manifold.
2 - you have the lights figured out
3 - radiator fan power?
4 - not really sure.... there is a line which goes UP to the hood for the hood light, and there are the horn controls down there on the driver side, as well as running lights and turn signals, but the plug could be for the outside air temp sensor too. Uncertain about brown wires or their use.

2 - good to go.
3 - it’s not the fans. I’ve got those connected and functioning. I noticed that the radiator shroud has a small connector. Maybe the male connector in the pic goes to that?
4 - hood light makes sense. Mine isn’t connected.
90% solved. I just need to figure out what the male connector in pic 1 is (unless it’s also AIR-related) and what the female connector in pic 3 is.
Thank you for the response!
