When i baught my car it came with a cold air intake. The only problem was its a custom piece of shit and i had to build it a bracket just to hold it in place. But any ways there is a plug that comes off of the tb that gose no where. It has a red/yellow wire and a black/green wire. I was just wondering what it dose and if it could be what is makeing my check engine light come on? Hopefully the pictures help.
