So am I right if I connect Bule on attached to P16 and P17 then red to pc5v?? were does the 220v come fromto drive the pump? I take it that the two brown wires are the on off switch but do they come fromthe pump or via a 220v feed?

One of the wires goes in and out of COM/NC on the side that gets switched.
Example:
220v+ve goes from feed+ to the pump 220v+ve.
220v-ve goes from feed- into COM, then NC out to pump 220-ve.

So the relay will turn it on/off on the low (-ve) side this way.
