Hello After spending last year having a ball with ender 3 Pro, I bought a Ender Extender kit I measured the 55mm on the 4040 Y axis. everything is done except the Y end stop limit switch is too short by 3". Creality went and used a 3 conductor plug and used just two outside pins. I have 4 extender wires with 2 pin plugs, no help to me.
