This afternoon while trying to route the wiring for a greddy profec B spec 2 I managed to pull one the connectors off. I will need to solder the wires back on again.

I would like to know which way round the wires are, the connector was the one that plugs into the main unit and connects the main unit to the valve unit.

There are two wires a green one and a white one, when your looking at the front of the main unit which side is the green wire on?
