I need help identifying where this plug is supposed to go. I had the blower unit out to replace the evaporator, and for the life of me I cannot figure out where the circled green plug is supposed to go. There is an identical one plugged in already, which you can see in the last pic.

Edit: it’s a 2001 LX.

Of course I didn’t take any pictures of it on the disassembly… that would make life too easy. Thanks for any help you can give me.

I believe it's for the recirculation actuator.

Thank you! That is exactly what it was. I had re-installed the ECM and couldn’t see that port missing its plug.
