Husqvarna 545125801 Throttle Cable Wire Harness 150BT 350BT 350BF Blower

Husqvarna 545125801 Throttle Cable Wire Harness 150BT 350BT 350BF Blower.

Restore Instant Throttle Response & Safe Engine Kill Control: Genuine Husqvarna Harness

Eliminate sticking throttle triggers, delayed engine acceleration, broken kill switch circuits, and exposed wiring on your commercial backpack blower. This Genuine Husqvarna Factory OEM Throttle Cable and Wire Harness Assembly (Part Number 545125801) is the complete integrated control conduit engineered explicitly for Husqvarna 150BT, 350BT, and 350BF backpack leaf blowers (as well as companion RedMax and Poulan Pro commercial units) . Operating a backpack blower with a kinked or frayed throttle cable restricts carburetor butterfly opening, cutting blowing power, while broken ignition stop leads create an immediate jobsite safety hazard.

Instead of fighting with generic cut-to-fit cables that bind along the blower tube or lack integrated ignition stop wiring, installing this authentic factory component ensures true OEM fit and function. Manufactured to rigorous Husqvarna commercial specifications, this assembly encases a smooth-gliding, high-tensile steel throttle cable alongside insulated factory engine ground wires inside a heavy-duty, UV-resistant corrugated protective loom. It features precision factory molded end fittings—including the throttle trigger barrel lug, carburetor swivel end, and pre-crimped bullet/spade electrical connectors—allowing direct, plug-and-play installation along the blower pipe without wire splicing or modifications.

This authentic factory replacement component is cataloged under Husqvarna OEM Part Number 545125801 (545 12 58-01 / Assy Cable Wire Harness / Throttle Cable & Stop Wire Assembly) .

🛠️ Pro-Maintenance Tip: Watch the "Accordion Elbow Loop & Idle Play Adjustment Secret!" Routing Secret: When routing the 545125801 harness along the blower tube, make sure to leave an intentional, gradual slack loop right over the flexible rubber accordion elbow! If the harness is secured too tightly across this joint, swinging the blower tube back and forth during sweeping motions will pull the throttle cable taut, causing the engine to rev unexpectedly or fatiguing the internal stop-switch copper strands. Cable Play Secret: After connecting the cable lug to the carburetor throttle rotor, check for 1mm to 2mm of free play at the joystick trigger before the carburetor butterfly begins to open. This ensures the carburetor returns completely to its mechanical idle stop screw when releasing the trigger.
