HELP.. I managed to get hold of a new metering unit for the S2 RST, before i fit her i just want to clarify one thing... The black box on the right of it, i think its the pressure actuator... The plug has broken and i had to put 2 spade connectors on them, I just want to know which way around they go... If someone can have a look to see which colour is on the left and which colour is on the right, from an above view of the unit.. Thanks guys.
