Hi. Ahmm, maybe it's an age thing but where does the green ended one plug into?? I'm using an aftermarket headlamp but it only uses the blue one. Surely, it connects somewhere..🤔 I just put on a new intercooler ..

 

Under the black headlight bracket there is the ambient temperature sensor that it plugs into.

 

Thank you sir. Makes complete sense now. Back when my pcm went bad they never plugged it back in.😄
