The wiring diagram on page 325 of the rebuild manual shows the two red and white striped wires being spliced together on the loom side of the connector so I guess it shouldn't make a difference which is connected to which (but I'm no electrician........................).
As I and others on here have said though, I recommend junking the OE part and fitting one of these
