on the odb 0 wire on the plugs were you cannot get to the pins as easy as the white plug i used a straigt ping and bent the tip of it with a pair of plires so it is at a 45 degree angle. and when you look at the plug head one you will see a row of hole down the center of the plug. i am not talking about the ones that the ecu pins go in but the ones in the middle. then you take your modified strait pin and you put the bent part of the needel towards the pin and press it into the little metal clip that holds the pin in the socket it is kind of a pain in the ass but with some patients and time they will come right out and the plug will be fine.
