Sorry the confusion,

What I'm trying to find out is which of these sensors dose what when it comes to wiring up the ecu ? I know one will be to the temp gauge and one to the ecu ( I presume) but, what dose what in the pic ? What I'm looking for is

The one under stat ( you can just see it ) housing goes to ?
The one on top of the stat housing goes to ?

Thanks in advance

Adder
