Wiring is really a personal preference but I like everything as neat as possible which is why I made a wire locker mount for the metal kit. You can find the files in the FYSETC Modified Printed Parts folder on my Github

Note-This will not work if you have the BLTouch on the rear of the carriage

Using 2x M3x6 button head screws and 1x M3x10 button head screw mount the Wire Locker to the Rear Plate

Insert the hotend wires into the wire loom.

If you have a 24" zip-tie insert it into the wire loom with the wires(not included with the kit). This will help keep the wire loom up

Using a small zip-tie, lock the wire loom into the wire locker
