the diagram/instructions that came with my active p.u. I'm installing this p.u. by itself in a strat body. You can see a picture of the diagram on my website: www.hampleman.com/guitar.htm. If I understand the diagram correctly, the red wire from the p.u. goes to the positive of the battery and the neg goes to the stereo jack. Also, the 25k pot has 1 side grounded and the common going to the stereo jack. I'm not real sure about grounding. Can anyone make any comments?
