This adapter allows you to add a standalone engine management system to your project that is utilizing factory 1996-1998 Ford Mustang wiring.

Ford Mustang 1996-1998 M.F. Plug and Play Adapter is compatible with the following:

  • 1996-1998 Ford Mustang 4.6L 2v/4v - Manual Transmission
  • 1996-1998 Ford Mustang 4.6L 2v - Automatic Transmission (4R70W)

Benefits:

  • Utilizes the factory wiring and sensors
  • Retain all factory instrument gauges
  • Retain all factory controls (e.g. cruise control and air conditioning)
  • Easy installation as most installations can be done in under two hours
  • 2 x CAN BUS connections built into the Main Harness

Now Supporting:

  • Coil Drivers are built into the adapter, meaning no external drivers needed.
  • Two channels for conversion of Variable Reluctance (VR) to Hall Effect signal. One channel is designated for factory Vehicle Speed Sensor (VSS). The other channel is open for use with customer modifications to wiring (e.g. it could be used for traction control by adding a front wheel speed sensor).

Optional Sensor Connections:

  • Fuel Pressure
  • Oil Pressure
  • Manifold Air Pressure
  • Flex Fuel

For the optional sensors we have wired our sub harness to work directly with Low Doller Motorsports sensors. 

Flex Fuel requires the use of a Continental 13577379 or 13507129 sensor.

I have a 1997 cobra with a Vortech v2 SI. Wanted to get the Holley but wanted to retain all my factory wiring and gauge cluster. I bought the EFI adapter from M.F Kustoms. It literally can’t get easier than this all plug and play. I highly recommend the adapter. 10/10 highly recommend. PS Danny is very helpful answered all my questions very fast. Thanks again Danny and MF Kustoms!
