Maker Select Plus BLtouch errors with 4.0.6

I rewired my bltouch for the probe port and flashed up to 4.0.6 this evening, but after doing so, can no longer home my Z axis. The self-test of the sensor works as expected. When connected via Repetier-host and issuing a G29 command, I am presented with the error

Error:STOP called because of BLTouch error - restart with M999

Upon issuing the M999 command and re-trying G29, I then receive

Error:STOP called because of BLTouch error - restart with M999
Error:Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)

The hot-end temp is reading nearly exactly what I would expect given my room temp, the bed temp is reporting a bit high, though nothing ridiculous, 30 reported vs approx 20 room temp, though IIRC that’s always been the case.

It means that there is a problem related to the white wire if the BLTouch.

:man_facepalming:t3: I had opened things up and checked that, but did not notice until I actually pulled the JST connector out that one of the pins had pushed backward out of the connector
