There are 6 plugs all told. 3 are for the ECU, 1 is for the dash, 1 for the other internal electronics and the 6th does not quite go though the dash and I can't remember but it is obviously not important. The connections in the Gallery that I put there will give you all the pinouts that you need for a gen 2. the wiring diagram will cover gen 3 and I understand that the other pinout are the same.
