Best purchase hands down

If you have a newer vehicle and you don't want to cut anything to hook up a aftermarket radio or amp then you need to buy a harness from these guys.

2018 Chevy Crew Cab Sounds amazing!

What can I say, other than the quality, engineering, and personal attention that goes into this harness means one thing! These guys definitely care about their product and it shows! The customer service is on another level as they answered any and all of my questuons for a flawless install in my truck!

Excellent product

I installed an aftermarket passive sub in my 2023 durango rt and the ANC had it sounding likecrap, installed the bypass harness and problem solved instantly.


Just installed and it works great!

Super simple to install in my 2024 GMC Sierra! Great customer service as I actually talked to a human with knowledge of what I wanted to do. Pure time saver!
