5.0 out of 5 stars Solid Pre-Built Fuse/Relay Box
Reviewed in the United States on December 31, 2023
Verified Purchase
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.

5.0 out of 5 stars Clean install
Reviewed in the United States on March 1, 2024

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!

3.0 out of 5 stars Back needs to be sealed with silicone etc.

No rubber seal on the lid, but it fits tight.

Would seal the back with silicone to prevent corrosion.

Other reviewers have helpfully noted the wire gauges and wiring configuration. I put it on my Kawasaki KLR650 motorcycle. It's holding up well.
