Here is the deal, I uninstalled a Speed Cal because I am getting a tuner. I can't for the life of me find the factory plug that goes back into it. The only plugs I can find is the black one that was plugged into the Speed Cal and the rear o2 plugs. Am I missing something???? I do not see where any wires have been cut or anything. I figured the black plug that the speed cal hooked to just plugged into the sensor......crap!
