# Horizon Fitness 4.1T Treadmill Data Wire Harness Cable (DC318)

## Product Introduction

The Horizon Fitness 4.1T Treadmill Data Wire Harness Cable is a replacement data cable for the Horizon Fitness 4.1T treadmill. This cable carries data between connected treadmill components, helping the machine’s electronic systems communicate during operation. If the original harness is damaged, missing, or no longer provides a reliable connection, this replacement part can help restore the proper connection between compatible components.

This product is identified by part number and SKU \*\*DC318\*\*. It belongs to the \*\*Data Cables\*\* category and is listed under the \*\*Horizon Fitness\*\* brand.

## Product Details and Benefits

The \*\*Horizon Fitness 4.1T Treadmill Data Wire Harness Cable (DC318)\*\* serves as the wiring link for data communication within the treadmill. A treadmill data harness can connect electronic sections of the machine so that signals can travel between the console, control electronics, sensors, or other compatible components. The exact connection points depend on the treadmill’s original wiring layout.

Replacing a worn or damaged data cable can help address problems caused by a broken harness, an unreliable connection, or a cable that no longer matches the machine’s original wiring setup. The replacement should match the existing part and connect to the same compatible treadmill components.

This listing provides one product identified as \*\*DC318\*\*. The available product information does not specify cable length, connector count, wire gauge, insulation material, color, or installation method. Review the existing cable and treadmill service information before ordering to confirm that this part matches your equipment.

## Compatibility and Applications

The DC318 data wire harness cable is listed for the \*\*Horizon Fitness 4.1T treadmill\*\*. It is intended for use as a treadmill electronic data cable and replacement wiring harness for that specific model designation.

This part is suitable for owners, repair technicians, and service providers working on a Horizon Fitness 4.1T treadmill that requires a replacement data connection. It is not identified as a universal treadmill cable, so do not assume compatibility with other Horizon Fitness treadmills or machines from different brands.

The product source also lists the serial number reference \*\*TM136-A05010004\*\*. Use this information, together with the model name and the original cable, when checking fit and application.

## Why Choose This Product

Choosing a cable with the correct model and part identification helps reduce the risk of ordering an incompatible harness. The DC318 designation gives you a clear reference for comparing the replacement with the cable currently installed in your treadmill. Replacing the correct data wire harness may help preserve the intended communication path between the treadmill’s electronic components.
