2023 ninja 400 quickshifter adapter

in EX 400
Hi,
I've got the QSK2_G quickshifter kit for EU spec ninja 400 '23 and installed, but it's not working. Once adapter connected to gear position sensor connector, bike can't read its gear and won't start at all. Might be incorrectly installed but I don't see any other connector housings are fitting this adapter except gear position sensor underneath ECU.
Anyone installed this please advise.
Thanks
