The user [will-stevenson](https://github.com/will-stevenson) drew my attention to the fact that you can use the G1-G2-G3 pins instead of the 2-pin header if you have H3 and H4 bridges (see: https://github.com/knutwurst/Marlin-2-0-x-Anycubic-i3-MEGA-S/issues/12). This gives you a cleaner solution that doesn't look so tinkered. To do this, you have to swap the 2-pin connector on the BLTouch sensor for a 3-pin.

### MEGA Pro wiring ### MEGA Pro wiring
The user [Stefan Kalscheuer](https://github.com/stklcode) draws my attention in [this ticket](https://github.com/knutwurst/Marlin-2-0-x-Anycubic-i3-MEGA-S/issues/210) to the fact that the wiring of the MEGA Pro is different and he has documented two solutions to elegantly connect the BL Touch Sensor to the MEGA Pro. The free "X-Stop" connection can be used if you either change the two lines **A5** and **B5** in the upper green connector, or change the `Z_MIN_PROBE_PIN` (2) to the` X_STOP_PIN` (3) in the source code.

One of the servo extensions is led out past the top of the board. So that nothing gets stuck. There is enough space in front of the connector for the cable. The circuit board can then be screwed tight: One of the servo extensions is led out past the top of the board. So that nothing gets stuck.

The three wires of the BL Touch sensor control the servo, which can extend and retract the tip. These must be plugged correctly onto the pins of the Trigorilla mainboard. It is important to note which board you have (TRIGORILLA_14 v1.0 or v1.1), since the pin assignment has changed here. So please don't just plug it in and hope, but check very carefully whether the pins are correct and you have selected the right board.

In order to properly connect the BLTouch to the Trigorilla Board, + 5V and –GND must be swapped in most cases so that the assignment on the board is correct. The plug must not simply be plugged in. The pins must first be removed from the connector and then reinserted in the order described above. + 5V is down, ground / GND in the middle and the servo pin up.
