I don’t knowIs there an opposite wire dangling that seems to fit?
It leads back to hvac controlThat connector looks factory, but the wire not so much. Can you tell what's on the other side? It kinda looks like the primary ground for the PCM, but I don't remember that having a connector. It just went straight to the negative battery terminal.
The thing that isnt working is the blower so was wondering if it goes to there and where to plug it inIf the vehicle is able to be powered, check the HVAC for what doesn't work. That will give you a start for trouble shooting. Knowing what doesn't work will help point to what component that goes to.
