RED WOLF AMP Amplifier Subwoofer T-Harness Wiring Kit - Speaker Connector Adapter Plug for 2014-2021 Chevy GMC Silverado Sierra Yukon - Easy Install Factory Radio Upgrade for Enhanced Bass & Sound System | Perfect for Car Audio Enthusiasts & Truck Owners

As reviewer James and Layla said - it’s worthless. One end plugs in and connects and the other, that connects to the truck side, doesn’t. It doesn’t clip into place. In fact the harness doesn’t even connect to itself if you try to do that. It’s like somebody just gave up after doing one end and somehow quality control just never bothered to look at this harness. Absolute garbage.I take it all back. Out of frustration - knowing I was about to mail it back - I start looking at it - knowing it SHOULD work. For the heck of it - I push, REAL HARD - not into my stereo but from harness end to harness end - and sure as heck, it went - I think the pins are also tight from the factory it seems like it won’t go when you try initially - and a lot of the reviews seem to say it doesn’t fit, and I admit myself it threw me initially. Came back to say I was wrong and I hope this helps. Headed out to the truck to try again now but I know it’s gonna click into place this time.
