Hitachi 0005473 is the hydraulic pump wiring harness in black corrugated conduit with a grey multi pin main plug and branch leads to the pump sensors and proportional solenoids. It is used on Hitachi ZX200-3 to ZX270-3 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 0005473 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.
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.
A little dielectric grease keeps water out of the plug on machines that work outside. Make sure the terminals are clean and tight first.
No. It is an aftermarket wiring harness made to replace the Hitachi 0005473. It is not made by the original manufacturer; the number only shows what it replaces.
