Makes installing a breeze for this canbus system with minimal splicing of the radio harness. ### ⭐⭐⭐⭐⭐ Worked amazing *by C***S on March 27, 2024* Was the perfect solution to my radio on my silver not turning on/off with my truck. Works great now even go som chimes and other dings I never new it had once I connected the harness to the radio. ### ⭐⭐⭐⭐ Harness does its job. Beware Amazon opinions on open box items. *by D***N on July 20, 2021* The harness did its job. Nothing really to complain about there other than the module is a bit bulky and takes up a lot of space. I unfortunately made the choice to order an open box item because it was half the price of a new one. The item was listed as being in great condition but was not in its original packaging. Well that was either a complete lie or a gross oversite by whoever inspects returns. The harness was chopped up, modified, included no original documents, still had bell connectors on al the wires from the last person that ordered it. I had to download the wiring instructions and Google pics of what the harness looks like new to repair it before I could install it. The Label on the module was so faded that it had obviously been installed in a car for quite some time so I am not even sure how it was was allowed to be returned. Bottom line, if its not new in box assume it is 1000 times worse than the condition description that Amazon provides. I don't think they actually have anyone inspecting them. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/8116290-metra-axxess-gmos-lan-01-lan-onstar-interface-for-non](https://www.desertcart.tw/products/8116290-metra-axxess-gmos-lan-01-lan-onstar-interface-for-non) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-06-03*
