Hey all! First time around here, but I'd been in search of some help. For some context, I'd been in the midst of attempting to connect a salvaged R61's Trackpoint to my new Corne Keyboard. Long story short..... I spilled excess solder over some of the smaller components of the trackpoint module, and had ended up deeming it un-repairable (with the current of tools that I have of course). In an attempt to keep the project going without having to wait on more parts to arrive, I turned to my Lenovo T570's keyboard. I'd been expecting to maybe find the Two-Piece Trackpoint mentioned here:

Would anyone happen to be able to know either the pinout, or how I could go about determining the pinout here? Sorry if it's a dumb question, I'm not the best with tracing small electronics but I'm trying to learn more
The thought I had here had been that if I were to grab the schematic for the PTPM754DR I might be able to trace out the RST pin, and somehow find GND, VCC, and DATA in the process, although I'm not certain if that's even remotely correct.
