Review on Optimized Wiring Harness: Metra 70-2104 for 06-Up GM Radios by Jason Hood

I recently bought a 2009 Pontiac Vibe, according to the wiring harness it is for a 2009-2010 Pontiac Vibe. After purchasing the head unit the head unit was faulty so I contacted the basement and got a replacement, no sound after fitting, I assumed it was the radio I just bought. After many problems I decided to buy a new JVC from Best Buy which comes with a free installation. The technician tells me there is a problem and he doesn't know why, but there is no sound in the car. It took over 3 hours for a professional team to find the problem. This problem was that the harness was not properly attached for every wire except two. Input of speaker cables with backlight output Unfortunately I do not recommend this product in any store where I have looked for a cable harness of this type. Attention buyers
