Multiquip 8983346920 PCV Heater Wire Harness - OEM Replacement Part

This PCV heater wire harness is a critical electrical component for Multiquip Super Silent generators, designed to ensure proper warning lamp operation during engine runtime. This harness was introduced as a factory update to correct a condition where the control panel warning lamp could remain dimly lit while the engine is running with no actual fault present.

Per Multiquip Service Bulletin GSP20210208, this resistor wire harness installs between the existing control panel wiring and the warning lamp terminals. Installation requires lowering the control panel to access wiring connections, removing the two wires with blue spade terminals from the warning lamp, attaching the harness blue terminals to the lamp, then connecting the harness red terminals to the original blue wires while matching wire colors (orange to orange, yellow to yellow). Some production units may have shipped with this harness pre-installed, so visual inspection is recommended before ordering.

Compatible generator models:

• DCA20SPXU4F
