wiring off road lights help

I got a pair of hella 500 lights that i tried to install today. I was succesfull until one of the final steps when i needed to tap into the headlight wire to get the "hot" wire to work. (the green wire that attaches to the middle of the switch) where should i attach this and how? Can i just attach this to the postitive terminal on the battery so my lights can work whenever?

I recommend hooking the green wire the + battery terminal. If you splice it to one of the headlight wires your driving lights will only work on which ever (low or high beam) that you splice into.
