Ok I have a. 3sgte st215 dr tweak did the wires but my obd2 doesn't work so I know what wire goes from the obd2 plug to the ecu but I don't know which pinout that wire goes to on the ecu..... so I know the ecu are almost the same as the 3sgte st205 only some things are different. I have th pinout diagram but it doesn't say..... so does anybody no which pin from the ecu is for the obd2
