Ford 1986 - 1995 5.0L Fuel Injection Wiring Harness Extra Length
This harness is standalone and is not intended to replace the OEM engine wiring. Standalone harnesses are intended to run the designated engine and transmission only, generally when swapped into another vehicle.
This harness is designed for the 1986-1995 Ford 5.0 (car) HO EFI engines. You must use the 1989-1993 MAF, Distributor, and ECM. 1986-1988 must add MAF (mass air flow) sensor. 1994-1995 must modify TPS wiring and change distributor. Harnesses do not include all the original connections for the original emissions but are available separate. Included with this harness is an 8 circuit modular fuse block and Ford color coded wires with labels for easy installation.
This extended length harness allows eight feet from the back of the intake manifold to where the fuseblock and ECM mount. Perfect for those that plan to mount these components under the seat or in the center console.
This kit includes:
- All new fuel injection harness with OEM fitment connectors and harness breakouts
- Diagnostic connector and check engine light
- Rubber grommet
- Mounting hardware
We HIGHLY recommend checking the online manual for the full list of required mating parts prior to ordering.
