SHIPPING POLICY

Tamerx Diesel Products ships via UPS Ground. Next day air shipping can be arranged for a reasonable price of anywhere from $50.00 - $100.00 depending on the weight of the product and your location. We will do everything we can to make sure that you get the service you need. We understand how important it is to receive your order as quickly as possible.
In most cases Tamerx Diesel Products only needs one address, as long as your product is shipping to the same location as your billing information. In order to eliminate credit card fraud, your billing information must match the credit card you provide.

The terms, conditions, and details of our warranty vary from product to product. Specific warranty details can be found below.

Tamerx Diesel Products provides a replacement warranty on all of our parts. The duration and mileage limitations of the warranty vary by product and are specified on the product's detail page/item listing.

Please note that the warranty covers replacement of the part and the cost of shipping the replacement part to you only. It does not cover any shop, labor, towing, or any similar or related costs. This is not a "money back guarantee".

If you experience a problem with your part or it is not functioning properly, the correct warranty procedure is to call us at (510) 257-1777 (8:00 AM - 5:00 PM ET Monday through Friday). Be sure to have your order number and/or other relevant order information ready so we can easily locate your order and resolve your issue as quickly as possible. From that point, we will review with you any troubleshooting steps that may need to be taken and other areas or systems that can be checked to rule out external problems contributing to your part's issue. If a replacement is determined to be necessary, we will then arrange for your replacement part to ship out ASAP and issue any necessary return shipping labels and/or documents.

As is the case for the majority of the diesel products sold on Tamerx Diesel Products, your part's warranty is active as soon as you install it. In some other cases, warranty activation is contingent upon you sending us your core (i.e., your old part). Tamerx Diesel Products will provide you a return shipping label for parts that have a warranty with a core return condition. When we have received your core return, the part's warranty coverage begins. We reserve the right to void the product warranty if your core is not received within the allotted time, or if it isn't received at all. If the warranty for the diesel part you are purchasing has a core return requirement, it will be clearly noted on the product detail page/item listing.

What is a Core Charge?

A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.

30 Day Core Charge Hold

You authorize Tamerx Diesel Products, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.

Electrical systems are the backbone of modern diesel engines, and the wiring harness is what keeps everything connected. The Cummins wiring harness serves as an organized network of wires, connectors, and terminals that transmit power and data between critical components. In aftertreatment-equipped engines, it plays a vital role in ensuring sensors, control modules, and emissions components communicate accurately and consistently.

  • Connects Key Engine and Aftertreatment Components
    The wiring harness links sensors, actuators, and control modules, allowing electrical signals and data to flow throughout the system.
  • Ensures Reliable Power and Signal Transmission
    By organizing electrical circuits into a single assembly, the harness helps maintain consistent voltage and communication between components.
  • Supports Accurate Engine and Emissions Control
    Proper signal flow is essential for the ECM to manage fuel delivery, emissions systems, and overall engine operation effectively.
  • Designed for Cummins Applications (2018–2024)
    Built to OEM 5417549 specifications, this harness is engineered for compatibility with Cummins engines and their factory-installed systems.
  • Protects Electrical Circuits in Harsh Environments
    With protective coverings and durable construction, the harness helps shield wiring from heat, vibration, and moisture common in diesel engine compartments.

The wiring harness may not be visible once installed, but it is essential to system reliability. In Cummins engines, a dependable harness ensures proper communication between components, supports emissions control, and keeps the entire engine system operating smoothly.

A wiring harness is responsible for carrying electrical signals and power between various components in a vehicle, including sensors, control modules, and actuators. Designed to operate in demanding environments, wiring harnesses are built for durability—but over time, several factors can lead to failure. Understanding these causes can help prevent electrical issues and system malfunctions.

  • Exposure to heat is a common cause of failure. High temperatures can melt insulation or cause wires to become brittle and crack.
  • Vibration and movement can lead to wear over time, especially if the harness is not properly secured.
  • Moisture intrusion may cause corrosion at connectors or inside the wiring, leading to poor electrical conductivity.
  • Physical damage from road debris, sharp edges, or improper routing can cut or fray wires.
  • Chemical exposure, such as oil, fuel, or cleaning agents, can degrade insulation materials.
  • Poor installation or previous repairs may result in loose connections or improperly protected wiring.
  • Aging over time can cause insulation breakdown, making wires more prone to short circuits or signal loss.

A failing wiring harness can lead to intermittent faults, warning lights, or complete system failures. Regular inspection, proper routing, and protecting the harness from heat and contaminants can help extend its lifespan and ensure reliable electrical performance.

Yes, excessive heat can damage insulation and affect electrical performance.

Yes, it functions continuously whenever the system is powered.

It allows different components to send and receive signals for proper operation.
