Great Item for my Ford F150
I needed a better way to wire the lighting on my Ford F150. This item was great! It has 6 connections. Very easy to wire. The relays work great just hit the switch and the lights jump on very bright! This fit right behind the battery and tie in was very easy. 1 ground wire and 1 battery line and your set. Just use your switches. I found that this was the best value by not having to buy each item separately. this comes in one easy package.

Great price and very easy to use
Makes wiring much easier, really well made overall. The grippers on the relays and fuses are tight, wire leads could be longer but are easy enough to work with. The leads are aluminum wire not copper unfortunately, but for the price it's to be expected. Excellent product for the price.

Good quality, tight connectors
My brother and I used two of these boxes to rewire a classic car. We liked the compact design and we bought an extra to fill one with relays and the other we filled all but two spots. We didn't need the fuses as we kept the OEM fuse block. We bought the bare assembly so we wired it ourselves. We have the proper tools to give great crimps on open terminals, we are very experienced in that task. The boxes are good and strong, plenty good enough to pass as OEM on a modern car IMO. What I don't like is that the relays are so tight together it is very difficult to get them out. We have to use a flat bladed screwdriver, often two at a time, to pry them out. The connection terminals provided have a high tension on the blades of the relays. It would be great to have some sort of tool to grip the relays from above so they can be pulled out more easily. Additionally the individual relay blocks that hold each relay snap in from the top of the box. As we've pulled out a relay the block sometimes comes loose, that's why we need to use two pry tools, one to hold the block down and one to pry on the relay. We placed the two boxes side by side, and the design for mounting to a panel accounts for this, the ears are staggered so they can be put side by side without having to change the height, a nice level installation. I would not say these are water proof, but they are quit tight. The bottom needs a tool to pry it off. Overall we are happy with these, just wish the connectors were not so tight.

This is a solid relay box. It’s easy to use wire in and so forth.

Well built fuse box, almost military style
Very well built all fuses including. A little big for my jeep but very well built.

No instructions.
It doesn’t come with directions that are in any way instructive. Company will not provide anything beyond the single page provided in the description. Installation is relatively easy, but the uneven length feet were a pain. Quality is good, however.

Works great
It doesn't specifically state that it comes with the fuses and relays, but it does, and ws very easy and a straightforward install

This item almost perfectly met my requirements. Great instructions & easy to fit. It has cleaned up my wiring & grouped all my fuses & relays in one spot. The only negative is that it’s a bit hard to remove the relays as they are quite close together. I would recommend this product.

Worked great. I used a battery terminal fuse and just wired it right to it so we didn’t have to install a bus bar and separate wire with fuse etc. Seems reliable and quality 12ga wire for lots of power to aftermarket heated seats and a rear truck cap defroster. Handles the amps well.

Solid. Don’t take it pre-wired if you have a project in mind and know how tu plug relays. I used it for my ls engine swap. Works perfectly and small enough for a discret fit.

Quality , don’t get to say that much these days

Used this for a 2jz engine swap to run coils, injectors, ecu, pwm fan controller, etc all on their own relays. Small and clean install. Very happy with the simplicity. Be sure to double check fuse sizes of the relay to what the load draws. They come pre installed.
