First of all, the quality is excellent and the instructions are straight forward. It is compact and easy to mount, and it allowed me to install seven electrical accessories that are all fuse protected without placing any extra stress or load on the factory wiring. ### ⭐⭐⭐⭐⭐ Works great for expanding circuits *by on Reviewed in the United States August 4, 2020* Easy to install, good quality. This item doesnt disappoint I needed more circuits for my 1999 Jeep Cherokee, and this item fit the bill. I'm so satisfied that I'll order a few more for other vehicles. Update - I installed another on my 2009 Jeep Wrangler, and am getting ready install another into a 1979 Ford F100. Great product, and install is super simple. ### ⭐⭐⭐⭐ Excellent Accessory for Adding Electrical Devices - Jeep JK *by on Reviewed in the United States May 15, 2019* I added this to my 2018 Jeep JK to handle accessory lights etc. I wanted to isolate my tinkering from the factory wiring system, and this was a great choice. I also wanted to be able to easily wire accessories as my Jeep JK customization develops.Pink wire goes to an ignition-on fuse tap (positive), 10ga red wire goes through an in-line breaker (supplied) to the battery, and the negative ground for the relay is at one of the screws on the fuse box mount. After that, you have a mix of constant-on and ignition-on positive feeds that you can use to power a variety of accessories.I routed all the unused wires along the back of the engine bay and ended near the hole in the firewall, tying everything up nice and neat. I also wired a bundle through to a Rugged Ridge switch panel inside. Next accessory install will be a breeze.The instructions were just okay. All you really get is a diagram and single page of text. Pictures would be nice, but it all worked out. The hardest part was finding a good place to mount the fuse block. ## Frequently Bought Together - Painless Performance 70207 Weatherproof Cirkit Boss Auxiliary Fuse Block, 7-Circuits (3 Constant/4 Ignition) - Alex Tech 25ft - 3/8 inch Cord Protector Wire Loom Tubing Cable Sleeve Split Sleeving For USB Cable Power Cord Audio Video Cable – Protect Cat From Chewing Cords - Black --- ## 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.jp/products/14724450-painless-performance-70207-weatherproof-cirkit-boss-auxiliary-fuse-block-7](https://www.desertcart.jp/products/14724450-painless-performance-70207-weatherproof-cirkit-boss-auxiliary-fuse-block-7) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-24*
