I'm doig a 4agze DLI MAP swap into an ae86. I think i have everything connect but the check engine light still wont come on and my car wont start. It'll crank. This violete wire comes out of the Diagnosis thing. Its still loose for I have cut off the 22 pin (gray) connecter. Should I connect this some where to get my check engine light to come on? Again this is a 4agze map DLI engine. Note on the wiring diagram, there is no mention of the violete wire at all.
