Review: Works good - Installed in my golf cart Review: This is an excellent wire harness for an aux light application - This wire harness is very easy to install, and has quite sufficient length for any application that I could imagine. I had surplus for my fog light installation that I doubled up and zip-tied out of the way. The most difficult part of the installation, as is always, was routing it into the cabin, and finding a place to mouth the switch. It comes with a "snake-skin" sleeve, that I think will offer very good mechanical protection. ## Features - UNIVERSAL FITMENT - Safely wire and control up to 400W of auxiliary lights, light bars, or other 12V devices with this high-capacity harness.

I had surplus for my fog light installation that I doubled up and zip-tied out of the way. The most difficult part of the installation, as is always, was routing it into the cabin, and finding a place to mouth the switch. It comes with a "snake-skin" sleeve, that I think will offer very good mechanical protection. ### ⭐⭐⭐⭐⭐ works very well *by B***H on August 7, 2024* this is a nice kit. i used it to run power to my on board compressor that i use for my air bags. the supply wires, heavier ones weren't long enough but i was able to crimp in a couple extension to the compressor. the switch is nice and lights up when turning on. It will require you to drill a 3/4" hole. and it will need a small key slot. for indexing. i had a small file the same thickness and was able to file the groove in the hole for it to fit very nicely. --- ## 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.it/products/151834381-ychow-tech-wiring-harness-1-lead-12v-40a-rock-switch](https://www.desertcart.it/products/151834381-ychow-tech-wiring-harness-1-lead-12v-40a-rock-switch) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-14*
