Works perfectly...much safer and reliable option than a fixed cord....because it's always connected without me having to remember to hook up. In most cases where I really needed a kill-switch connection, fighting a fish, deploying down-riggers, I found myself unhooking the kill switch because it wouldn't reach. Peace of mind and real added safety. ### ⭐⭐⭐⭐⭐ Very clever , *by C***K on February 21, 2025* I installed on a 1949 40’ Chris craft twin gas Hercules engines. The instructions are pretty vague on wiring but options are a closed grounding or open grounding to shut the engine circuit. I wired closed when activated to two relays, one for each engine to open the ignition circuit to shut the engines off. Don’t buy the multi engine connector, it says outboards only, i had to return it. It works perfectly. ### ⭐ Missing parts *by S***L on March 2, 2024* Box appeared to have been opened, no power cord in box. There was also no instruction but don’t know if it came with any. Needed for boat asap. --- ## 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.co.uk/products/186380239-acr-olas-guardian-wireless-engine-kill-switch-and-mob-alarm](https://www.desertcart.co.uk/products/186380239-acr-olas-guardian-wireless-engine-kill-switch-and-mob-alarm) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
