At the moment I just have the black wire capped. And I just ran the blue wire into the green wire (vtec solenoid wire). It's not grounded and that works. If your getting code 21 you probably spliced the two wires together:doh: You need that green wire to continue to the solenoid. I am actually going to ground the black wire sometime this week. Just ahven't got around to it. And hey it works without being grounded
