Does your C5 Corvette have Hyper Flash / Hyperflash or a faulty OEM Flasher?
Get one of these Hyperflash Harnesses from us and solve those issues in as low as 20 minutes!
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.
- Solves problems with your OEM flasher
- Permanently fixes the problem you were temporarily fixing by toggling the hazard switch until the turn signals worked again
- Solves hyper flashing / rapid flashing caused by LED Taillights or LED DRLs without using hot load resistors.
- Simple 20-30 minute Plug N Play installation with a #15 Torx Driver and the included instructions with pictures.

The correct one delivered new and in box. Shipped quicker than expected!

Brand new in sealed bag, correct product delivered.

Good deal, comes as described!

Arrived in perfect shape

When first purchasing the kit, it was very straight forward. I told them what I was looking to do, they directed me to the exact kit with everything needed included.
I recently had an issue with one of the struts, and FIP very quickly responded and handled everything with Silvers. New strut arrived at my doorstep within days.
Highly Recommend ordering with FIP.

Delt with this company online. Quick shipping and quick to call about my order to get it solved. 10/10 all around

Set of 3 hood vents installed on my 03 Z06, great product, fits great and pulls out the heat 🥵

Brian at FI Performance always goes above and beyond to take care of customers. I am a repeat customer and will continue to use them for all my needs. Thanks again Brian, amazing as always!

Exactly what I needed for my lowered C5. Full range of adjustment and quality made product.

Got a great product. In a very timely manner very happy

Great experience, order got messed up and Brian made sure to get it fixed and kept me up to date by texting me.

Exactly what I needed and had it next day

Customer service was great. Order shipped quick. Great value and the change to the car was better than expected. Wife no longer braces herself for the expansion joints and other Ohio road issues.

Brian was AWESOME to deal with, I changed my mind a few times on what I wanted to do with my c6z.. You can go down an endless rabbit hole when you get into these cars “while I’m in there “He was right there with updating pricing and I couldn’t ask for more.. Parts are parts and they will fail but it’s the service that sets the bar for a big purchase.. I haven’t driven the setup yet as it’s still being built but I’m sure he a phone call away to get it sorted..
