Factory OEM Harness Found!

This was a unique factory stereo harness that had me going CRAZY trying to locate the correct harness. I have been in Automotive management for 23 years and have watched electronic technology worm its way into everything related to the Automotive Industry. The days of "poking and proding" wires to find current have been long gone because this ancient practice invites corrosion and resistance a place to begin life. Metra's wonderful product allowed me to make a quick and simple connection and finish this job without disrupting my factory connectors. "Plug n Play." I will never look at anything but Metra's product line again! Thank You!

Great Service very quick shipping

This made installation of my Eonon M1U easy as pie to install,didn't have to worry about getting wires mixed up. Not many companies have parts for my 1984 Buick Lesabre SONIC came thru for me would recommend them to all my friends. Stop searching the web for your electronic parts if SONIC doesn't have it you probably don't want it anyway!

Perfect!

This wiring harness is perfect fit. Installation time only took a small bit. For my application, this wiring harness is a hit!

Ordering from Sonic is a breeze. These people are not sleaze. Sonic knows their stuff! They are not gruff.

If you want your car stereo to be a perfect fit, order from Sonic. Then your car stereo will be symphonic. Because if it does not fit, you must acquit

Sonic is the best, the hell with the rest!!

Loved the product

I loved this product. It put me at a level of relief knowing that if I wanted to return to factory I could with no hassle. I love how easy this product made it to put an aftermarket radio in my car.
