Hitachi 4449447 is the main hydraulic pump wiring harness: a corrugated loom with branch leads to the pump solenoids and sensors, each ending in its own sealed plug. It is used on Hitachi ZX200-3 series excavators. This aftermarket version has the same mounting and electrical connector as the original, so it plugs in and bolts on where the old one came off.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Intermittent faults and warning codes
Chafed, crushed or corroded wires in an engine or main harness give faults that come and go: sensor codes, a rough running engine or a machine that will not start. When several sensors fault at once, look at the harness.
Heat and rodent damage
Harnesses next to the exhaust and turbo go brittle and crack, and rodents chew the insulation on machines that stand. A new harness is quicker than repairing many wires.
Burnt or corroded plugs
Green corrosion or melted pins in the plugs cause high resistance and false readings. Replacing the harness renews every plug at once.
Fitting tips
Disconnect the batteries first, photograph or label every plug before removing the old harness, route the new one along the same clips and away from hot and moving parts, then clear the fault codes and test.

Yes, it was made for the Hitachi ZX200-3, and 3 more listed under compatible equipment. Check the old wiring harness is marked 4449447 or one of the cross references, because makers change parts between serial ranges.
On the Hitachi ZX200-3, there is no fixed interval. It is changed when it fails, and many fail from water in the plug or chafed wiring rather than wear.
A fault code for this circuit, readings that jump or stay fixed, or a part that does not respond with power at the plug.
Read the fault codes, then check the plug and wiring for corrosion or a broken wire. A wiring fault reads the same as a failed wiring harness.
Yes. Many machines have 12 V and 24 V versions of the same wiring harness. Check the old part or the machine plate before fitting.
No. It is an aftermarket wiring harness made to replace the Hitachi 4449447. It is not made by the original manufacturer; the number only shows what it replaces.
