Overall, a very nice product that does what it's supposed to do. Good quality and compact design. BUT ... the wiring diagram provided is not consistent with how it's actually constructed. Also, not consistent with standard 4-pin relay color wiring convention (yellow-load (87), white-trigger (86), red-12V (30), black-ground (85)). They had the wire colors connected to the wrong terminals. I had to take the unit apart and re-wire to standard wiring conventions. Also, be carefull when removing the top cover. One of the snaps can break easily.

Nice build, good clean wiring, leads not long enough, back wiring completely exposed (kind of defeating the purpose of having the top enclosed), unclear what type of relays are installed (turns out they are wired backwards to most typical relays), wire bundles out the bottom protrude making it hard to mount it flush on anything because the flex of the plastic housing.... Again defeating the purpose of having the top enclosed and the bottom open to the elements.

Used this to add multiple fog lights and light bars to a truck. Was able to attach neatly in the engine compartment and made for a factory looking install. Super easy to wire and it is what you need for a professional look that a novice could install!

I have to assume this housing was designed for a specific application and then marketed as a universal product because the mounting holes are staggered in a very odd way. I ended up having to use all-thread and a series of nuts to hold the box on the mount. Otherwise a good quality product. Relays have held up for several months under daily use.

For the price, this is a solid box!Having the 4 relays and extra fused power slots is a bonus.Another reviewer already mentioned how it's wired so I won't go into that part, but 2x red wires are main power, black is the daisy-chained ground, white is your trigger wires, yellow goes to your relayed devices, and the blues are just regular fused power.I used this in my 2002 VW Golf for a couple sets of fog lights, underhood lighting, and a lift pump. I wanted to clean up the battery terminals.As you can see in my images, I basically connected the 14 AWG power wires together, which gives this entire box around 40-50A rating. I'm protecting the entire box with a resettable, 40A breaker as a "just in case". From the breaker to the battery I just made an 8AWG jumper which can also handle 40A.The box mounts up nicely with some M6 screws.Couple things to note:Box is NOT waterproof. So place accordingly.As well, the included fuses are cheap. Probably won't last long but I'll run them until they go.
