just did this yesterday. cut apart a miniature keyboard and took out the touchpad. Had to cut off the wiring to the kayboard. I cut out a square section of the control panel I had to make, under the thumbpad keyboard. Then I glued the touchpad board under that flush. Then I soldered two momentary switches (red and black mini) into the little right/left click controller board and put them into place next to the touchpad.
No announcement yet.
Custom touchpad with right/left buttons and thumbpad in armrest
