- Confirmed LS300 Fitment — Verified for the Multiquip LS300 hydraulic concrete pump; check your model code before ordering to confirm compatibility.
- Full Circuit Restoration — A damaged or failed wire harness can cause intermittent faults, control failures, or pump shutdown; replacing with EM517994 restores dependable electrical communication across the system.

A wire harness is the organized bundle of electrical cables and connectors that carries power and control signals between the engine, hydraulic controls, and operator panel on a concrete pump. On a machine like the LS300, the harness is critical to coordinating pumping cycles, pressure controls, and safety shutoffs. When a harness degrades — through abrasion, moisture intrusion, or heat exposure — it can cause erratic operation, lost control signals, or complete electrical failure, making timely replacement essential to keeping the pump running safely and consistently.
