Can you be more specific, WM covers different timers & control systems.
There used to be a couple of different motor plug kits that came with butt conns and wiring, not used one for ages and it was never listed in the manuals.
Hotpoint were never ones for supplying much harness info.
There is a motor plug kit still available, a 169309 but that may have the earlier type of motor plug. ( picture on Masterpart web site ). Should still fit with the odd lug removed though.
The later motor plug is available, it is a 1601400, you really need the special pliars to push the wiring into the slots on these plugs .
