The seller happily helped me when I had a problem.
"although the colors do not accurately follow the picture I just numbered them from the plug to the board, which was from left to right (on plug) 1-5 I had the colors (white-1, black-2, yellow-3, blue-4, red-5). on your mainboard plug into D11 (3,1,2) with 3 facing inward of the board. the 2nd plug will be plugged into Z+ (4,5) with 5 facing inward towards the board. after that remove your old sensor (no jumper is required) and install the new one.
once that is done you will need to flash the screen with new files onto it and then plug the printer into a pc to do the mainboard firmware. both must be done for the BT touch to work. once put back together test the sensor on yourself to verify that it works, to verify that it will stop."
