Harness works great on my 2018 Silverado.

This harness is nice. Just add a Line Output Converter to it if you have an amp that uses low level inputs.

I waited over 2 months from another company and only got a reply from them once I filed a PayPal claim. These guys had my order to me in a week.

This says it only works with 2019+ trucks, but I took a gamble on my 2018 since the pin out looked the same between them. Works great.

Perfect 2022 silverado refresh LTZ

After waiting 3 months with another harness manufacturer & being fed BS excuses i decided to cancel & look for other options. Wish i would have found SGS sooner & i could have had my system installed 3 months sooner. Good quality harness all plug &play. Ordered speaker level output and used an alpine MvR-500 didnt even need the remote wire. SGS will be my go to for sound eq from now on

Poor quality. Wrong pins. Didn’t work.

The two wires spliced were wrong. Not speaker wires. I had to cut and splice the correct wires. Waste of money. 2023 Silverado ZR2.

2024 Ultimate Denali Dually

Bought this harness for my 2024 Ultimate Denali Dually and was worried it had the ANC mic but it does not and works perfectly for a simple plug and play very happy with this harness

Well worth the money

Without this, installation would be nightmarish, works great, fast and easy.

Amazing

Well worth the price

First this is a quality piece, second, it was the easiest part of the install. I see a few comments that mention it's price but when you take into account that it negates the need for an LOC, is custom made, and gives you the plug and play piece of mind, it's more than worth it.

2015-2020 GMC YUKON/YUKON XL

I used this on my 2016 gmc Yukon XL I used the speaker 4 pin high level and the harnesses worked well with the factory amp (BOSE System) the only down side is that the remote wire didn’t work and I was troubleshooting for a whole day then I jumped my remote wire to the 12v+ on the amp then I realized it was the remote wire so ran my remote wire to the front near the front driver side door there is a fuse box right there. The YouTube video is linked below to the remote wire installation I used a bussmann atr fuse tap and a 10 amp atr fuse to the factory.

2022 Yukon

This product worked perfectly to allow me to add an amplifier and subwoofer in my 2022 Yukon. The harness is well made and looked like the factory wiring harnesses. Truly made this install plug and play. Price is a little steep but that usually comes with custom products.

Custom Made T-Harness that provides you the subwoofer signal plus a remote turn-on to upgrade the bass in your truck, with a high-quality plug and play solution.
