Connector pin-out diagram of a 1989-95 mass air flow (MAF) sensor labeling +12V, ground, MAF-RTN, and MAF terminals.
Part of 1987-1991 Ford Bronco Wiring Diagrams
This document is a pinout diagram for the electrical connector on the 1989-95 Ford Mass Air Flow (MAF) sensor. The drawing shows the oval sensor connector face with four labeled terminals in a row, identified as pins A, B, C, and D. Callout lines link each pin to its circuit function: Pin A carries +12V power, Pin B is GROUND, Pin C is MAF-RTN 9 (the MAF signal return, EEC pin 9), and Pin D is MAF 50 (the MAF signal to EEC pin 50). The caption at the bottom identifies the applicability as the 1989-95 Mass Air Flow (MAF) sensor. A reader can use this diagram to identify which terminal on the MAF sensor connector serves each function when testing the sensor, diagnosing wiring problems, or performing a mass-air conversion. The diagram does not include wire colors, resistance/voltage specifications, or part numbers, only the pin letter positions and their circuit names. It was uploaded to a 1990 Ford Bronco gallery, and the stated 1989-95 range covers that vehicle.
