Intro
The Creality V4.2.2 and V4.2.7 boards have a dedicated 5 pin header on the board that can be used for the Creality BL Touch kits. You can also use 3 of those pins and the Z endstop port if you have the 3+2 pin wiring harness. Our Unified 2 firmware is setup to use the 3+2 wiring pinout by default but there is also an option called CREALITY_V42X_BLTOUCH_ON_5PIN that changes the firmware to use the 5 pin header. Below are details on wiring your BL Touch to these boards with the 2 different methods. Neither method is “better” than the other, they both work the same.
5 Pin Header Wiring

If you are using the 5-pin header only then plug your 5 pin BL Touch harness plug into this socket on the board. You will uncomment the BLTOUCH, CUSTOM_PROBE, and CREALITY_V42X_BLTOUCH_ON_5PIN lines and enter in your probe offsets in the CUSTOM_PROBE section.
Make sure that the wiring on your 5-pin plug matches the pinout on the board. Creality is known to wire them wrong, and this can damage your board. The header is labeled (from left to right) G, V, IN, G, OUT. Check your plug wiring per the below information:
- Black to the G pins
- NOTE: Sometimes blue or brown are used for ground wires
- Red to the V pin
- Yellow/Orange to the IN pin
- White to the OUT pin
If you are not sure about the colors on your harness, contact the place of purchase for tech support on their wiring harness.
3+2 Wiring Pinout

Using this wiring is as simple as making the connections as shown above, uncommenting the BLTOUCH and CUSTOM_PROBE lines, and entering in your probe offsets in the CUSTOM_PROBE section. If you are using the Creality Metal BL Touch bracket the offsets are in our help center article.
If you are not sure about the colors on your harness, contact the place of purchase for tech support on their wiring harness.
