So following on from that Peter the motor should park if you apply 12 volts to the motor terminal. You could do with borrowing a set to test your theory before shelling out. I guess you may be lucky. I did buy a set off ebay for £15. Cant remember what they were listed as but it wasn't X19, so look a bit wider than that. I looked at the plug colours and plumped for this set on the basis that they were the same as the X19 plug colours and when they arrived the wiring colours matched the X19 layout. Worth a punt on that basis if you see a set not listed as X19.
