ah cool thanks...i'll see if i can get it working from that.

fredster:

Nice picture, but what is "the hole in the middle"?

The red one on the x+/X+?

If I wanted to use just the x/y, where does the power hook up?  Do I have to de-solder the left mouse button to find the ground?  I can't seee where the +5v is at in the pic.  Have a plan view labled?

Blakey:

I thought I made it perfectly clear when I said "The 3-pin detector draws 5V from the middle pin". So if you removed the detector you would have three holes. The 'hole in the middle' is thus 5V. Tap your 5V from there. Or if you're too scared, tap it off your power supply.

What is x+/X+? The red/yellow pair is x+/x- and the blue/green paid is y+/y-.

In case that still isn't clear enough have another picture:

fredster:

Sorry, typo, ment X+/X-.  

That picture diagram makes it perfectly clear.  I understand now it's the middle pin in the detector group, either detector group.  Ground on the switch group.

I appreciate your quick response!
