Hard Top demister wiring

Didn't get too much info when posted elsewhere, so we'll see whether the techies have an answer?

I have put an aftermarket demister on our NA hardtop which is on a 2002 NB8B. I'm having trouble working out the wiring. I've done a search on the is forum and Miata.Net for an answer, and I can't seem to find one.

Now I'm aware of the cutoff switch which disables the demister when the softtop is down - I presume this is on the car side of the connector? I think this is where my problem is. I couldn't get hold of an NB demister plug and loom (softtop side) so I have replaced the plug with a different 3 pin one from Jaycar. I've had a look at my softtop wiring, and the black / white stripe wire doesn't appear to go anywhere - it perhaps just ends inside the loom cover somewhere? Certainly there's only the black and black / red wire which actually connects to the demister that I can see.

So, where does the black/white wire go to on the demister side? If nowhere, then presumably my problem is that the softtop down cutoff switch is stopping the demister working, so how do I bypass / fix this? BTW I checked the demister light came on with the softtop up, so the circuit is working

Presume someone else has had this problem???

Any help appreciated
