Ford uses a MAF that is self contained. Inputs are gnd & Vbat. The output is a
isolated ground and the analog voltage signal. I wish I could be more specific
but someone is currently borrowing my book. It is important to select a sensor
that is reasonably sized for the CFM of the engine. An oversized sensor will
have poor resolution at low flow. A MAF that is too small will limit the
engines WOT performance. IE: bigger is not always better.
Hope this helps,
