Ford 4.6 & 5.4 Wiring

1993-1996 Ford 4.6 V-8 Modular Engine:
This engine was introduced in 1993 in the Mark VIII. This is Ford Motor Company's new modular design engine which can utilize some of the same parts to create a lower horsepower engine used in other Ford models. The 4.6 engine in the Mark VIII utilizes a thirty two valve, double over head cam design to create 280 horsepower while the 4.6 in other Ford models is a single overhead cam engine that produces 205 horsepower. The Mark VIII engine has intake manifold runner control solenoids which operate plates which are closed below 3000 RPM so the engine is running on two valves per cylinder. With no air delivered to the secondary intake valves, economy and emissions are improved at low RPM. Above 3000 the plates open increasing air delivered to each cylinder for more power on demand. The 4.6 engine has two ignition coils with each coil firing four cylinders. The 4R70W transmission is used behind this engine. Factory ECM can be used in factory configuration.

1996-2003 Ford 4.6 / 5.4 V-8 Modular Engine.
Beginning with the 1996 Mustang and 1997 passenger cars, Ford began installing Passive Anti-Theft Systems (PATS) in their ECMs. Short of installing all the components and sensors from the donor vehicle, the only way to defeat PATS is by reflashing the ECM to completely remove it. The Detail Zone can perform this for you. During the reflashing process, we can set up your ECM for aftermarket fuel pumps, electric fans, reduce fan switch on temperatures and disable certain emission sensors if your local smog laws permit. We are not performing performance tuning at this time and suggest dyno tuning for these modular motors.

The early 4.6's had a coil pack for each bank of cylinders but with the 1997 passenger cars and the 1999 Mustang, Ford went to coil on plug (COP). The Detail Zone can wire up all late model 4.6 and 5.4 engines. If you have questions please give us a call or e-mail us.
