2005 Ford Focus Pricing and Specs

Just for starters, the ZX4 is a four-door sedan, while the ZX3 body is the three-door hatchback. At the very least, that will mean differences in the wiring loom as regards door-courtesy and boot/tailgate lights. Cars will have different wiring looms depending on their transmission, too, so even if the engine is the same in both cars, the loom might not be.

Then there's the more basic question of whether they're actually the same model of Ford Focus. Ford Australia switched to the all-new second-gen Focus in April 2005, and if your 2005 Focus is that newer version, the wiring will not be compatible with the 2001 model. But even if they're from the same generation of Focus, swapping a wiring loom from one car to another involves many, many hours of work.

It will all depend on when in 2005 the Focus in question was built. Ford changed from the Mk1 Focus (LR model) to the all-new Mk2 Focus (LS model) in April of that year, so an early-build car will not be the same as the 2009 model, although a later-2005 one might be.

These two versions of the Focus were built on different wheelbases and platforms, so there may not be too much interchangeability. Certainly the bodies were quite different, so panels and interiors won't be interchangeable at all. Even the steering systems were different model-to-model. The Mk1 used conventional power-steering, while the Mk 2 switched to electro-hydraulic power-steering.

The compliance plate under the bonnet will tell you all you need to know about the car's build date. Visually, the earlier car had a much more angular style at the front with almost triangular headlights, while the later car was more upright and conventional looking.

There’s a distinct line in the sand here. If the 2005 Ford Focus you’re referring to was a late Mark 1 Focus, then yes, the headlights should interchange with an earlier Focus as both cars were more or less the same. At the time, Ford was making use of what was called its `Edge’ styling philosophy which was all hard lines and sharp angles.

However, for the Mark 2 Focus which came along in May 2005, Ford had softened the styling considerably, and the headlights of an early Focus will definitely not fit the Mark 2 model as they are a totally different shape.

What puzzles me most is where you managed to obtain a 2000 Focus as the car was not introduced into Australia by Ford until late 2002. The car did exist prior to that, but not in this country. Perhaps you’re buying headlights online from an overseas seller. If that’s the case, make sure they’re for a right-hand-drive Focus as they’ll physically point the wrong way if they’re for a left-hand-drive car. They’ll also be technically unroadworthy if that’s the case.
