Installing a new stereo in your semi truck? This 16-pin ISO wiring harness makes the job way easier by connecting your aftermarket radio (like Pioneer, Kenwood, JVC, Sony, or Alpine) to the factory wiring in your truck without cutting any original wires. It's compatible with a huge range of semi trucks, including Freightliner, International (2000-2018), Peterbilt (2006-2018 models like 579, 567, 386, 379), Volvo VNL (2004-2016), Mack (2012-2018), Kenworth (2008-2020 T270/T880), and more. It also fits some Volkswagen and Mercedes-Benz vehicles, so it's quite versatile. The harness comes pre-terminated with butt connectors, so you just match the colors, crimp, and you're done—no soldering needed. It's designed to work with popular radio series from Pioneer (AVH, NEX), Kenwood (DDX, DNX), JVC (KW models), and Alpine (ILX, INE). Whether you're upgrading to a touchscreen, adding Bluetooth, or just replacing a broken unit, this harness saves you time and keeps your truck's wiring intact. A must-have for any truck owner or installer looking for a clean, reliable stereo installation.
