wiring it is no different to a normal map sensor....

1 wire is 0v
1 wire is 5v
1 wire is signal between 0-5v

simple really as imatrukas said its a temp sensor as well so that would also give you 1 wire for the temp signal.

as on a cossie pressure and temp take a common 0v from pin 11 i guess there is no reason why you couldn't use this sensor in your plenum to do away with the 3 bar and the manifold absolute temp sensor - guess it would depend on scope and spec of the temp range as its for a truck LOL...
