IAT & expansion cable

Hi Amvegeta.

I would be inclined to do what Brett suggests.  If you are tuned off MAP and not using the MAF sensor, this can be disconnected and used as a spare wire or two in the harness already going to your ECU plug.  The ground should be a 'signal' type ground from the ECU, or common it with something like the TPS ground (same thing).

If you are lucky enough to have the revision 1.1 circuit board, this has AN Temp 3 as a common with the expansion plug and B136-19.  This way you can take the pin from the MAF position in the harness plug and put it in to B136-19.  If not, you will still need the expansion cable.
