good luck dude... use the search function here, or check my threads, i made an inquiry about it some time back, but let me assure you, you're in for a big headache.. unless you wire it directly to the switch
With a Duncan, you should go: green and bare to ground. (You did that.)
Red and white together. (To the switch.)
Black as the output. (To the volume pot.)
The way you have it now, I believe you have one coil of the humbucker out-of-phase. The sound should be fairly weak and lacking bass.
