The Horizon Fitness CST3 TM119-1US Treadmill Wire Harness Cable is a preowned data cable for the Horizon Fitness CST3 treadmill. It carries the part number and SKU **DC518**.

Product Details and Benefits
This product is a treadmill wire harness cable, listed under the **Data Cables** category. Its primary purpose is to provide the correct cable connection within the treadmill’s wiring system. A functioning harness helps the related treadmill components communicate or connect as intended. Replacing a faulty cable can help address problems caused by a damaged or unavailable wire harness, provided the replacement matches the equipment and original part.
The cable is sold in **preowned condition**. Because it is not new, the item may show signs of previous use. Buyers should review the product photos and compare the cable’s connectors, layout, and overall appearance with the cable currently installed on their treadmill. The product page identifies this item as **DC518**, which makes the part easier to match with service records, parts lists, or an existing cable marked with the same reference.
This listing covers the cable itself. The available product information does not specify dimensions, connector details, cable length, materials, color, or included accessories. Do not assume that additional treadmill parts or installation hardware come with the order unless the listing states otherwise.

Why Choose This Product
A correctly matched replacement harness can provide a practical way to restore the original cable arrangement without replacing the entire treadmill.
