I recently started a Voron 2.4 R2 build with a kit from Formbot.
Included in the kit:
TAP
Can bus
Manta M8p V2.0

For some reason, the kit did not come with a cable harness for the Y-endstop. OK, so I have to build one. Not a big deal.

Documentation says I have to connect the Y-endstop cable to the M2-stop end-stop connector(s).
Since the switch is a two wire switch and the M2-stop is a three pin connector, I am wondering about the connection.

The Manta Pinout shows this connector as: PF3 G +5v
I am going to assume that PF3 is a board mnumonic , G is ground and then +5v.
I am also going to assume that pin one (1) is to the left and is not connected, center pin is ground and the pin three (3) 5v is on the right.

Can anyone tell me if this is correct?

I am also going to assume the TAP is the Z-stop.

I'm not sure what you mean by a "board mnumonic". PF3 is the Signal pin, aka the pin that's actually connected to the MCU, and PF3 is its pin ID, such as taken from the actual processor's datasheet, which is also how klipper identifies it.
Standard Endstop switch wiring is to wire signal & GND. So you've actually got it exactly backwards. You wire Signal (PF3) and GND. you ignore +5v.

Tap is a probe, not an endstop. (though it can provide both functions, via klipper's Virtual Endstop feature)

oh also, I *believe* the lack of endstop wiring in the kit is actually because formbot defaults to sensorless homing

Thanks for the reply. I figured it out.

I had to take all the elctronics off and rotate the alignment 90' for the wiring to fit. While doing this I was able to look at the underside of the board.
Once I saw this I understood what was going on, AND, I found the Y-endstop cable, which the way it is wired confermed my suspisions. PF3 will be grounded when the signal needs to be acitve. 5V pin is not used in this instance.
