Thanks in advance!
If you have the 5HP19 with and MS43 ecu, everything I did in this write-up applies. I did look at the post you provided. I would purchase the 4-wire clutch switch and the associated clutch master cylinder. The new price is a little steep IMO so I'd look to source this from a junk yard. The 4-wire clutch is an update from the 3-wire and used a magnetic sensor (hall effect) to determine when the clutch is depressed. The associated master cylinder has a magnet attached inside the housing that provides the input to the clutch switch. That's how I'd approach it.
