This conversion harness from Aeroflow Performance is used when wanting to upgrade from the factory map sensor toa large 5 bar transducer pressure sensors on your Ford Falcon Barra BA/BF engine. This plug-in adapter loom allows you to plug and play an upgraded 5 Bar transducer/pressure sensor into a standard BA BF engine loom with no soldering or wiring necessary. It will allow you to also retain the factory air temp sensor. We recommend purchasing the 5 Bar Transducer/Pressure sensor (sold separately AF49-1551).
