yes it's the heater outlet and ecu temp sensor section of the thermostat housing, located to the left of the exhaust :thumbup:
I will be removing the entire mechanical water pump and pipework, the new ewp will be fitted somewhere near the gearbox with the pump outlet connecting (via a pipe) to a new blanking plate/pipe fitting on the block, a remote thermostat housing or an ewp controller will be used - not sure which yet.
