Hi Tricky,
here he is a photo of one of my connectors.
the blue and yellow wires go to my switch8 controller which throws the point blades.
the red and black go to the track/bus wire
the green to the frog on the point.
it does matter which way the blue and yellow goes to the switch8 or other controller to throw the point blades, but a quick test beforehand will sort that out, good luck.
