@fcwilt yes.

@jcwild I'm not sure how much additional help I can be, but i am also running a genuine BL Touch on a Maestro board. I just went and checked my connections against yours, and your wiring is correct. Also, my bltouch wiring is ~ 24" long, with 1 JST connector in the middle, so i wouldn't think that the wiring itself was too terribly sensitive. I retract this, and after reading what @Phaedrux has been saying, i agree there must be ghosts in the wiring Do you have the means to re-crimp a new one?

Edit:
I've pasted the probe section of my config. Hopefully this will give you a starting point for troubleshooting.

; Z-Probe
M558 P9 C"^zprobe.in" H5 F1500 T8000            ; set Z probe type to bltouch and the dive height + speeds
M950 S0 C"zprobe.mod"                           ; create servo pin 0 for BLTouch
G31 P500 X0 Y-43 Z2.35                          ; set Z probe trigger value, offset and trigger height
M557 X0:117 Y-6:81 S23.4                        ; define mesh grid 

Quality of Life Improvement:
I would suggest setting up a macro for resetting the BLTouch in the event it ever enters an error state. (eg. if you crash the probe on deployment.) Especially when troubleshooting, it'll come in super useful!
