FuelTech FT450 pinout diagram with wire colours

Where this comes from

Only FuelTech's own documents. Pin names and notes are written exactly as FuelTech writes them.

How we checked it

  • We start from the pin table in FuelTech's manual for this ECU: pin, wire colour and function.
  • Every pin is read again in a second FuelTech document: its harness manuals, which list each ECU pin with its wire colour, or for the FT700 its quick reference. A script compares them pin by pin.
  • A pin is only shown when the second document gives the same wire colour and function. FuelTech names its general-purpose wires by colour and number (Blue #1 is blue output 1), so the number has to match too.
  • Labels, notes and wire colours are written exactly as FuelTech writes them.
