The au manifolds use a combined air temp and map sensor. Im not sure if its compatible with the e-series ecu's.

Assuming it is, you need to work out what wires are for the map and what are for the air temp and go from there. Should be able to work it out with a multimeter.

well as i dont want to risk killing my ecu doing the trial and error thing..

i got a bit of a update .....
i rang the wreckers where i got my engine from and they said i can swap the au manifold for a el one which should have the 2 wire sensor..

can anyone confirm that the el has the round plug with 2 wires for the air charge sensor

Get the EF/EL manifold. The AU temp sensor has a different temp/resistance curve and will not work with E-series ECU's.
