Alright. I've got a Synaptics touchpad here out of a Dell Inspiron 1100, and I'm not sure which pins are the SDA/SCL pins...There are 6 pins - 1 I have found is GROUND, two are for the buttons ('B1' and 'B2'), and the rest must be SDA, SCL, and +5V. Can anyone help me out here as to what is what? Thanks!
