Well, I don't know whether I'm right or wrong, but I'm planning to connect the water pump secondary outlet (the one that used to connect to the
heater) straight into the inlet manifold connection (which used to take the pipe from the heater.)
I remember someone telling me that this bypass connection is useful for something or other...
...mind you, I'd love someone to tell me that this connection is unnecessary, as it will save a piece of pipe flapping around and getting in the way
of the plug leads.

The cooling system requires that extra 'bit of hose' so that it can do exactly what it does, BYPASS the system. Theoretically you could do with out
but it is better left on.
Consider.
You start your engine from cold, and the water pump starts turning & pumping water. This is only true if you have a bypass hose (normally routed
through heater) because your thermostat should be closed (cold engine). Because you have no bypass there is static shock pulsing in the cooling
system, ie the pump is trying to flow the water around the engine but it cant go anywhere because the outlet pipes are blocked (thermostat & bypass)
so you then start getting a thermal shock heat build up around the cylinders and combustion chambers, the normal result of which is either a cracked
head and/or a blown head gasket.
You could block the pipe and then remove the themostat, this would give you a slow warming up and result in similar problems because the thermostat
shape forces the water to flow in a controlled manner around the cylinder block thus avioding hot spots.
Hope this answers your questions.
Enjoy.

I just knew there was a good reason why I did it that way...

Mine go to the Heater.
Cheers

Note to all: I really don't know when to leave well alone. I tried to get clever with the mods, then when they gave me a lifeline to see the
error of my ways, I tried to incite more trouble via u2u. So now I'm banned, never to return again. They should have done it years ago!

work things out -----------
Role on the weekend , for the next piece of mental torture
