Mouse -> Happs trackball hack

Every mouse that I have put my meter to has -5VDC running through it's veins. The trackball needs +5VDC. Will running the wires from the detector solder points on the mouse harm the +5VDC circuit on the Happs PCB's? I have ordered the OptiPAC, should be in next week, can't wait. My main reason for doing the mouse hack is for my own knowledge. I have seen several pages and it looks so easy, alas all my mices are cursed with negative voltage.

Please enlighten, confused and annoyed.

Gord.
