plugs on engine loom?

There's 2 plugs at the back of the engine I can't find where they go.
They are between the coolant plugs and the standard oil cooler plugs?
One is the same as the det sensor plug?
Also there's one by the lambda sensor at the front of the engine, its a small white plug?
It hangs down there the aircon pump would of been. could it be off that?
I can't get any pics up because my camera is bust

the two at the back stu will go to ecu temp sensor (thats a twin plug with red top)
the single spade one goes next to it and is the temp gauge sensor

the one at the front goes nowhere as that would have been to ac compressor so just tape it up

Thanks Bob.

its not those 2 plugs tho they are already plugged into the sensors.
they are further down towards the standard oil cooler.

only other thing they can plug onto is the iacc valve which is roughly in the centre behind the plenum, think it has 2 pipes coming out of it (possibly one) thats a doublr connector
reckon the single spade goes to oil temp sender next to oil pressure sensor with rubber boot on it

ah, youve sparked my mind Bob, thanks.

one is for the presure sensor and the other is to the iac which i cant conect until i put the plenum on lol

Thankyou sausage
