Terms of sale, installation requirements, and liability information
HHC engine harnesses are direct replacements for the original factory wiring harness. They restore your vehicle's wiring to like-new condition using upgraded materials, but they do not alter, enhance, or modify your vehicle's electrical system behavior.
A new harness will not resolve driveability issues caused by other failing components, including but not limited to: the Camshaft Position Sensor (CPS), Injector Driver Module (IDM), injectors, Injection Control Pressure (ICP) sensor, glow plug relay, Under Valve Cover Harness (UVCH) connectors, or PCM.
If you are experiencing driveability issues, we strongly recommend diagnosing the root cause before ordering a replacement harness. See our Diagnostic Checklist for common 7.3L Powerstroke failure points.
Installed harnesses cannot be returned. Once a harness or any module has been connected to a vehicle, it is considered installed and is not eligible for return or refund. This policy exists because installed harnesses cannot be verified as new or resold.
Uninstalled harnesses may be returned within 30 days of delivery for a refund, minus a 15% restocking fee. The harness must be in its original packaging, with all modules and components included, and show no signs of installation, grease, dirt, or damage.
To initiate a return, contact alan@hardcoreharnessco.com with your order number. Return shipping is the buyer's responsibility.
Defective products are covered under warranty and are not subject to the restocking fee. See our Lifetime Warranty for details.
By completing a purchase, you agree that you have read and accepted these terms, including the return policy and OEM replacement disclaimer. This acceptance is recorded at the time of checkout.
If you experience an issue with your order, please contact us directly at alan@hardcoreharnessco.com before filing a dispute with your bank. We are committed to resolving issues quickly and fairly.
Filing a fraudulent chargeback (e.g., claiming a product is defective when the underlying issue is a misdiagnosed vehicle problem) is a violation of these terms and may be contested with documentation including your checkout acceptance, shipping confirmation, and tracking records.
While HHC harnesses are designed for direct plug-and-play replacement of OEM harnesses, installation should be performed by a qualified automotive technician or an individual with experience in automotive electrical systems.
Automotive electrical work requires proper tools, knowledge of vehicle systems, and attention to detail. Improper installation may result in vehicle damage, electrical malfunction, or safety hazards.
If you are not comfortable working with automotive electrical systems, we recommend having a qualified professional install your harness. The cost of professional installation is minimal compared to the cost of diagnosing problems caused by improper installation.
HHC harnesses are designed to work with properly maintained vehicles with functioning electrical systems. Before installation, ensure:
HHC is not responsible for damage resulting from bypassed, missing, or incorrectly rated fuses, or from pre-existing vehicle conditions.
HHC harnesses are replacement parts designed for the specific applications listed on each product page. Do not:
TO THE MAXIMUM EXTENT PERMITTED BY LAW:
HHC's total liability for any claim arising from or related to HHC products shall not exceed the purchase price paid for the product.
HHC shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to:
This limitation applies regardless of the theory of liability (contract, tort, negligence, strict liability, or otherwise) and even if HHC has been advised of the possibility of such damages.
Our Lifetime Warranty covers defects in materials and workmanship. If a harness fails due to a manufacturing defect, we will repair or replace it.
However, warranty coverage does not extend liability beyond the harness itself. If a defective harness causes other damage, our liability is limited to repair or replacement of the harness, not consequential damages to your vehicle or other property.
By purchasing and installing an HHC product, you acknowledge that:
You agree to indemnify and hold harmless Hardcore Harness Co., its owners, employees, and agents from any claims, damages, losses, or expenses (including attorney fees) arising from:

This agreement shall be governed by the laws of the State of Georgia.
If any provision of these terms is found to be unenforceable, the remaining provisions shall remain in full force and effect.
