...actually, I was saying pins 3 through 8 get used for power injection.
The DLA wiring scheme uses the pins 3,4,5 (white/blue, blue, white/green) for +12V and 6,7,8 (green,white/brown,brown) for ground.
To further complicate things I use the Holiday Coro wiring scheme (since I learned about power injection first from David Moore). This scheme uses the striped wires for +12V and the solid colors for ground. (easier, IMO)
