12-Slot Fuse Relay Box: A Comprehensive Solution with 6 Relays, 6 ATC/ATO Fuses, and 41 Metallic Pins for Automotive, Jeep, Boat, Car, Marine Engine Bay Review

This fuse box works great and is actually very useful. It has a relay connector that has been replaced with newer relays and is completely unusable. It also doesn't have the option of simply making a power hub inside. I also ran out of fuse slots very quickly and they only give one slot per slot and NO extras it seems so be careful.

This is a very good fuse and relay box for the money. It works as advertised and all parts pictured were included. I didn't think there would actually be 5 relays, but one relay was included. The bottom part where the wiring goes is a little tight. I only used this box for a fuse and 3 relays. Using it for all 5 relays requires very careful wiring to make everything fit.

Adding electrical upgrades to a Fiat 79. It includes new headlight relays, a fuel pump safety relay with minor modifications and a starter relay in one compact package. My only concern is that the picture shows the fuse holder terminal on busbar strips of 4, but I received individual clipped terminals. I need to find another way to daisy chain power all the fuses I need. It is not possible to crimp 2 #10 wires into one connector.

Pretty easy got what I needed to replace the LS. I will drive this car on the street. If it was an offroad app I wouldn't trust it. The relays seem pretty weak so I will buy stronger relays. I have no way of proving if they are good or bad, but I don't want to risk it, they just seem cheap and material. The downside would be that I would put them on my car and then get stranded on the street which would be very unfortunate.

Knowing what I know now it would be worth buying the relay/fuse box already assembled. You need to know the size of the wire you need and then the length after you cut the length of the wire and burn the ends and it is very difficult to connect the wires to the relays and fuses. You also need Maine bus bars and relays and it takes a lot of time to get everything together. So if you don't mind doing all that, then yes, it's worth the money for this kit.

The relays are too wide to mount without cutting their tabs or deforming the box. I got lucky but didn't screw it up, but no extra ports. The bottom cover must be modified to allow the cables to exit from the side chosen by the user. Mounting tabs are terrible, no spacer included to accommodate misalignment. There is no O-ring on the top and bottom covers. I ended up just coating all the contacts with dielectric grease. The only thing I really liked is that they have a pull tab where the wires…

There are no instructions for this item. So unless you're familiar with terminating spade terminals and fuse links, you'll have a hard time figuring out what to do. I have experience with relays and wiring so I knew what to do once I saw the items and details. In general, the relay box looks beautiful and very neat. My small complaint is that the bottom cover isn't big enough to hide the wires and jumpers. I had a hard time closing the bottom cover due to lack of space, but I figured it out.
