This is a life safer when upgrading older car wiring and adding a aux fuse box to the circuit! Simple and easy install!

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.

I've installed two of these wire harnesses, the best way for adding lights and accessories to anything.

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.

I used this product to add electrical accessories to my Dodge Ram truck. 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.

Ive been using this product for over a year to add accessories to my Yamaha Rhino. Its mounted under the hood and is subjected to mud, snow, salt, its frequently submerged in water, rocks...and its held up remarkably well with no failures. I would highly recommend the Painless 70207 for any off-roader wanting to add accessories to their rig.

I purchased this unit to add accessories to my Tacoma. All the wires were clearly labeled and the instructions were easy to understand. The hardware was a little on the cheap side. My biggest complaint was the appearance of the fuse block and sealant applied to the back side. It was very messy and caused the mounting feet to be uneven. For a company that claims to be the leader in the industry, I would expect more. Other than those couple of complaints, the fuse block has functioned properly every time I turn on the accessories.

Such a great purchase! I love this thing. I considered getting a cheaper one but it was money well spent. The wires are clearly labels and colour coded. It works great for adding accessories into my Chevelle.

Its pricey you could probably go cheaper if you bought components at a local electrical store - auto store.

good product. you could potentially create your own idea of this very easily. but painless never disappoints. everything in the box to install easily. I used this on my army truck for lights, gauges, radios, GPS systems, transmission lockup control and a bunch of other stuff. works great. no issues.
