Thing that you couldn't ignore for installing custom audio
Great price and quality. I'd like to customize sound in cars I owe. Without harness it looks pretty weak and non-professional. Personally I've used only of one this set.

This product is recommended.

Harness did not Match my 2011 Hyundai Tucson Limited
The 2 plugs in this harness did not match the ones on my Tucson even though it specified that it was compatible. I tried getting support and all I ended is buying one that was recommended by your technician. At least it looks like it will fit. Img 6974 is the one I received and Img 6975 is what is in the car.
Unfortunately, your tech support gave up on me. And I feel like I was left hanging with this now.
