12V Relay Fuse Box Prewired Relay Box 12v Automotive with 5pcs 5pin relays 1pcs 4pin Relay 6 ATC/ATO Blade Fuse, Universal Waterproof Fuse Relay Box for Automotive Car Truck Marine Boat

Instructions are clear (for a trained electrician like myself). Construction is well designed, though it should be considered "water resistant, NOT waterproof). I took it apart to examine how it's built: SOLID.The package is surprisingly compact, well thought out, no shortcuts taken. I'm so impthat I've ordered a second one, and will be rewiring my car (with lots of aftermarket electrical loads), as this setup is vastly superior to anything else out there.Only issue is that I'll need to upgrade my alternator from 120 amps to 200 amps, to properly power everything... but that's no fault of this wiring solution... LOL.It is an excellent value for the money, better then anything else I've seen, for this type of equipment. It's the BEST deal I've seen out there, bar none.BUY it, you won't regret it.

Great little relay box that comes pre-wired. I would say it's probably decently weatherproof but I don't personally know if I would stick it somewhere that got direct water/weather exposure. I don't have too many gripes about it other than 1 thing. Its great that it comes pre-wired however, the length of the wires could be a little better. Depending on where you're mounting it and how you're wiring everything up it places alot of connections in a very small area. The wires are probably 8" at best and most of that is covered by the wrap. Personally i removed the wrap and wished i didn't have to but with my installation there was no way I could get around that. It would be nice to have another 10-12" of length at a minimum on this as it would allow you to really play with the install setup. Either way other than that small wish it works fantastic.

I like the fact that this gives my greater ability at customizing my 1982 International S1900. I am building it into a long distance RV hauler by modernizing it with electrical niceties like power windows and locks, but also specializing it with additions like A/C and service lighting.This relay box is going to make it super simple to add in the lighting and other systems that will benefit from a modular control point.The six relays each control one function. That function is then protected by its own fuse. The schematic provided makes it incredibly easy to wire it all up. The wiring is all packaged so installation should be very simple. I have a gang of LED lit switches coming to control this.I checked each circuit on the bench and every one of them work, I can't wait to get all of it installed.I am considering sealing up the bottom where the cabling comes out. I doubt ambient moisture or rain will get in, but I feel it is too big of a hole and don't want anything getting in to cause corrosion.All in all, a GREAT product. Is in the plans to make my customization easy and very professional looking!

I’m wiring in a number of additional features to my early 90’s Jeep. They were handled by a rats nest of wires and relays. All was fine until I needed to troubleshoot. Then it was like an archaeological expedition. Stumbled upon this item looking at new relays and I must say I’m super happy with it. It looks SOO much better under the hood and the next time I have any kind of accessory issue it’s one-stop shopping straight to this box. Great deal for the money.

This relay box is vastly easier to wire than the ones that are barebones. Even at a higher price (of course) just the time involved makes it much worth the cost. Also prevents wiring mistakes and frustration. I'm very keen on automotive wiring but much prefer to save time and frustration by using this box.

Bought this to expand the fuse / accessory options in my '23 4Runner. The fuse box looks very well built, but one of the bottom lid retaining tabs was broken. I didn't notice this prior to attempting the install (took a while to get all of the random parts ordered in) and I missed the return deadline. Would guardedly recommend, but be sure to inspect it upon arrival.

The is a handy accessory for wiring multiple 12V accessories in a car/truck/suv. It has the option of splitting the fuse box into two different fuse banks, depending on your needs.

No instructions. Might as well build the relay box yourself. Might save the headache
