Is this product suitable for 'positive earth' cars or only negative earth?

I'm not absolutely sure but this item comes with a basic wiring diagram and I think that simply reversing the polarity on the switch should suffice. I'm quite surprised that a positive earth car still exists. Most will have been converted years ago.
