1997 Volvo 850 t-5 Dangling Connector Near Turbo Charger

I was working inside the engine compartment and noticed an unconnected electrical connector underneath the ABS module. It had oil and dirt on it and appears to not have been connected for a while. I am always working on the car and I could have disconnected it to get access to something but just forgot to reconnect it. Might anyone know where this two-pin connector goes? It is not the boost controller.

It might be the heater for the PTC. What color are the wires?

Geeze. I see the two pins plain as day now. Thank you for straightening me out. I didn't know I had a PTC let alone knowing what it is. So, having it disconnected has done what to my engine performance?

Again, TIA!

Nothing. It is part of the PCV system. I'm not sure if the ECU even monitors it.
