## Overview

The Corvette Envy C5 Hyper Flash Fix harness is a waterproof, vehicle-specific solution that stops rapid LED turn signal flashing by replacing your OEM flasher with a custom spec unit. Assembled with genuine GM Delphi connectors featuring Terminal Position Assurance, it guarantees a secure, vibration-resistant connection. Designed for quick 20-minute plug-and-play installation using a #15 Torx driver, this harness optimizes flash rate for C5 Corvettes without the heat risks of load resistors. Note: incompatible with Euro Taillight conversions.

## Description

Assembled with parts consisting of original GM Delphi connectors, TPA's and terminals to ensure the best fit with your original harness, combined with a custom spec'ed flasher to deliver the optimum flashes per minute rate for your C5 Corvette. This harness uses TPA (Terminal Position Assurance) equipped connectors just like the original GM Delphi connectors to ensure that each terminal has a "locked in", assured connection. The TPAs can only be inserted if each terminal is completely seated in the connector housing. This will make sure that the terminals will not back out of the housing due to natural vibrations. *** Does not work with the Euro Taillight Conversion ***

## Customer Reviews

### ⭐⭐⭐⭐⭐ Effective Fix - Not as straight-forward of installation as expected.
*by J***S on October 15, 2024*

This cured my hyperflash after I installed LED taillights. I wasn't sure what the result would be with this harness since I still have the old-school incandescent bulbs in the front markers. But this worked well.I'm not completely lost when it comes to working on my C5 but this install did take longer than I expected based on other reviews here. There was a required interpretation of the instructions and 'shimmying' of panels to get everything sorted out. Overall, still 5 stars and a great product with an easy install but instructions could have been clearer.

### ⭐⭐⭐⭐⭐ It works!
*by R***  on January 16, 2025*

I purchased this item in conjunction with led bulbs for my headlights, turn signal, and parking lights. For those of you that are unaware, it keeps your new led bulbs from hyperflashing / flashing fast. It's working great 👍

### ⭐⭐⭐⭐⭐ Simple install, great instructions with color pictures, Impossible to goof it up
*by D***L on August 25, 2024*

Simple, fast install, great instructions with color pictures, Impossible to goof it up. If you put LED bulbs in your C5 to stop the melting issue from those light being on constantly, you NEED this. Could I build one? sure, but this was cheap and made it an easy decision. The only difference I discovered was my dash panel screws were T15, not T10 as stated in the directions. You NEED this!
