Metra 70-7304

When replacing your factory radio with an aftermarket car stereo, the Metra 70-7304 wire harness is necessary for a quick and clean installation. It eliminates cutting your OE radio plug. After connecting it, your install is as simple as the wires will color-match and easily connect to the aftermarket stereo. Without the Metra 70-7304, you must cut the OE radio plug and manually test each wire to connect to your aftermarket receiver. In addition, because you do not have to cut your OE radio plug off, the Metra 70-7304 allows you to reinstall your factory receiver if necessary. A great example is if you sold your car, but wanted to keep your aftermarket radio and reinstall your factory stereo receiver. We also recommend the Scosche BOBAZT for a quick connection that is sure to last.

  • Compatible with select 2010-2021 vehicles from Kia, Hyundai

Metra 70-7034 wiring harness used in 2014 Kia Optima- VERY happy

This wiring harness worked very well with a 2014 Kia Optima. I was disappointed with the Metra website for the wiring diagram. I had to re-write it so I could understand it. The speaker wires portion of the harness was very easy- color matching. Connecting up the Axxess remote control had some questionable wire colors that slowed the installation process. Definitely would purchase this item again (it was included in the purchase price of my Kenwood DDX770).
What is a wiring harness? The deck has a plug-in with pigtail wires. This wiring harness is spliced to those pigtails and plugs into your vehicle's harness for the factory sound system. NO cutting of factory wires. Deck-Splice- harness connection- factory harness connection
