C8 Aftermarket Seat Wire Harness - Error Free

Upgrade your C8 Corvette with the aftermarket or track focused seats you’ve always wanted—without the headache of dashboard lights / warnings or any lost functionality.

Installing aftermarket seats in the C8 traditionally triggers a host of issues, from annoying airbag and seatbelt lights to disabling the Hard Top Convertible (HTC) operation. Our custom wire harness provides a plug-and-play solution to bypass those errors, keeping your dash clean and your Corvette functional.

Designed to fit all C8 years and sub-models (Stingray, Z06, E-Ray, ZR1 and Grand Sport). We build them to order to ensure it fits your specific vehicle and its packages perfectly. 

Key Features

• Error-Free Dash: Completely eliminates airbag and seatbelt warning lights caused by seat removal.

• HTC Fully Functional: Retains full operation of the Hard Top Convertible system, no lockouts or lost functionality.

• Tailored to Your Build:

  • Choose: Driver Side only, Passenger Side only, or a complete Driver & Passenger set.

  • Choose to retain OEM seat belt buckles and pre-tensioners, or remove them if you're only using aftermarket harnesses. 

  • Choose to have your harnesses modified or purchase new harnesses. 
    • New harness orders CAN NOT be cancelled once the special order is placed with GM. This is a FINAL SALE

How to Order: Core vs. New Harness

We offer two convenient ways to get your custom harness:

1. Send-In Service (Modification): Mail us your existing OEM seat wire harnesses. We will perform the custom modifications and ship them back to you ready to install.

2. Purchase New (Upcharge): Want to keep your original harness perfectly in tact for resale? Select this option, and we will source brand-new OEM GM harnesses, modify them, and ship them directly to you. Timeframes will increase while we wait for the harness to deliver from GM.

Important Notes

• To ensure the system functions correctly and keeps the dash free of errors, the OEM seat belt buckle must remain plugged into this harness.

• There are a couple of easy to access seat modules that will need to be removed from the OEM seats and transplanted - detailed instructions will be provided upon purchase. 

• We will need your VIN so we can guarantee fitment as GM has changed the seat harness throughout the years - regardless if we modify your harness, or a new one is purchased. 

• Once the purchase is complete, we will send you detailed instructions on how to remove your existing harness and any modules that may need transplanted.
