To get this to a usable state, I knew that I’d have to cut the case down to size. It shows up in System Profiler as “Apple Internal Keyboard / Trackpad” and I can use the default trackpad preference pane to set the gesture functionality I want. Luckily enough, I guessed correctly the first time, because when I plugged it in to my keyboard, it just work. Next, I twisted and taped the lead wires to the USB cable’s wires, having to guess which data wire went to which lead. Suffice it to say that it was a nerve racking ordeal. Several times I had to unsolder a wire because it was touching multiple test points. I melted the solder onto the lead wire, then used the iron to melt that on to the board. I have seen reference to a “needle tip” which probably would have been just right. I was using an iron with a small tip, but even smaller would have been better. I prepped some multi-colored wire and fired up the soldering iron.

Since I did not know for sure which of these leads connected to which USB function, I decided to solder lead wires instead of directly to the USB cable. Once found them all, it was time to solder. I used a combination of tracing the circuit board and guessing to find the match, then used a digital multimeter to verify my guess. Since there was no way that I could solder to the leads themselves since they were so small, I needed to find which test points (the gold spots on the board) connected to which lead.

Since this is how many wires are in a USB cable, I made some assumptions about which leads were associated to which USB functions, namely that the left one that connected to ground, the right one to power, and the other two were the data cables. Looking at the small ribbon connecting to the controller board, I noticed that it only had four leads.
