Carerra controller plug diagram

Got my new Carerra track from PM. Only 1 of the track tabs was broken! Sux. But I expected more.
So I have one of the PM controllers. It has the scalextric plug. I bought a PM Scalextric to Carerra conversion. Problem is, the Carerra track is not marked as to RED, BLACK, and WHITE. I fear hooking it up wrong would damage the controller.
When looking at the Carerra track, there are three holes where the three prongs from the factory controller plugs in. Two holes are together with a space and finally the third hole. My issue is identifying which is which.
Is there anywhere I can see a diagram of this. Sure would hate to fry a $130 controller whilst experimenting.
All help is appreciated.
