Manuals clarification please

[testack18]

A few days ago it seems Bigtreetech updated Chaoticlab's CNC TAP V2 build guide in github:

In that manual they stated that TAP must be connected to BLTouch port utilizing the signal pin:

Is this only for CNC Tap V2? As in BTT's own repo their own docs still says TAP must be connected to the 4 PIN port beside the X limit switch and the manual does not differentiate the V1 and V2 TAP:

This is a bit confusing for me. Please clearly state which one is the correct or if this is only for Tap V2.

Thank you in advance!
