Review on 🔌 Scosche VW03B Power/Speaker Connector & Wire Harness: Compatible with Select 2002-05 Volkswagen Models for Easy Aftermarket Stereo Installation, Color Coded Wires Included by Sean Sheppard

It connects well and works great with factory speakers. No change required. However, there is a catch. I have a 2006 Jetta MK5 and there is no ignition power source on this harness as the main unit is powered on by logic from CAN-BUS. This way the stereo won't turn off when you first set it up and plug it in. You must cut the ignition source power cable and connect it to another source. I found one in the fuse box and used a fuse for it. Now it is turned on and off with the key.
