So the pesky rats/mice struck again! Ideally I would like a replacement black part of plug as the splicing I have done does not seem to have worked. Know these were manufactured to fail as the insulation contains soy t0 help with biodegradability!! Go figure. Any way I think I got the wires correct, top left splice, nearest red slider, Blue/Black, Top right; Black/white and bottom left Black/purple. Anyone who knows if this is 100% correct or if I got anything wrong, because I still have a missfire and rough running with error codes.
