Makes Stereo Install EASY
This made the installation easy in my Camaro. The harness does its job by making the car's wiring work with the up to date stereo head unit. Quality feels good in the hand, time will tell about durability. In my experience, these go in and are forgotten about because they just work and stay working. Good for the price!

Perfect fit for my 2002 Silverado.
This plug fit as promised, and makes wiring an aftermarket radio much simpler. I would recommend this to anyone who is going to upgrade their stereo. A must have part.

Works in 93' Chevy Lumina
This worked well for my 93' Chevy Lumina Euro edition. However, one of the 4 plugs that was supposed to connect into this did not fit. The plastic tabs meant to guide it simply didn't line up right. That mystery plug had two wires running to it that I do not know the function of. However the other end of this plug, where you are meant to wire the radio to, had no wires coming from this mystery plug. So if it had fit into the hole, it still wouldn't be connecting to anything.So I wired the existing cables coming from this harness to my new radio deck, and all the wires match up perfectly with nothing left to run to this mystery plug (I had figured if I had extra wires at the end I'd discern what this mystery plug was for). Turned on the car, radio works perfectly with this mystery plug left disconnected.So I wrapped it in electrical tape and simply stuck it into the back of the radio cavity with the rest of the wires. Harness worked perfectly for function, just one strange plug in my car is now disconnected but it's impacting anything at all.
