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.

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 Volvo EC220D excavators. Check the old wiring harness is marked VOE14635718 or one of the cross references, because makers change parts between serial ranges.
On the Volvo EC220D excavators, 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.
A little dielectric grease keeps water out of the plug on machines that work outside. Make sure the terminals are clean and tight first.
Usually. Clear them after fitting and run the machine, so old codes are not mistaken for a new fault.
No. It is an aftermarket wiring harness made to replace the Volvo VOE14635718. It is not made by the original manufacturer; the number only shows what it replaces.
