The original wiring is long gone and I've tried to simplify things with a very basic loom. Getting the wipers to work correctly has always been a challenge. I found a diagram on the net for a Lucas set up, which is essentially very similar to the 205. I've reworked the wiring diagram to identify & connect the pin outs on the 205 motor. The circuit has always worked well on low speed and parks correctly. High speed is always jerky however. I've tried spare motors with the same result. Perhaps a electrical boffin can see the errors of my ways?
