I really like this fuse box for the most part and I am willing to give it a 5 star review. I like the way it mounts under the hood and looks like a factory feature. I like the pre-wired fuses and relays. I likes having a box that allowed circuits with relay and fuse or just a fused circuit. Draw back is only 3 fused circuits and 3 relayed circuits. I feel it should have been at least 6 fused circuits. If you want a negative trigger for any of the relays you will have to rewire the relays as needed.

4 stars only bc the relays are only a 1 Terminal Replay. Meaning you can only hook up 1 load to the replay. You can buy a 2 Terminal Relay and have 2 Loads & it does have provisions to put in a 2 Terminal Relay.So with this unit you can only have 2 loads. I'll be getting 2 Relays with the 2 Terminal so I can Run 4 Loads total. Still a good product.

We ran this on our micro sprint race car to control electric fuel pump and water pump. Compact and lightweight

recently installed the Pre-Wired Fuse Relay Box in my truck, and it has been a game changer for managing my electrical systems. Here’s my experience with this product:User-Friendly Design:This fuse relay box comes pre-wired, which made installation incredibly straightforward. I appreciated the clear labeling on the terminals, allowing for quick connections without confusion. Even for someone who isn’t a professional mechanic, the installation process is simple enough to tackle with basic tools.

This small factor relay / fuse box fits the bill perfectly for my project. Restoring a vintage truck; after upgrading the electrical system with a larger alternator, I want to add accessories inside the cab. In comes this little box that fits perfectly in a hidden space behind the dash. It will be fed from a dedicated power source from under the hood and triggered by a key-on (switched) accessory line.The build quality is good and proper size copper wire is used. It came with clear instructions that show how it is pre-wired and intended to be used. Now for the controversial items mentioned in other reviews. I completely agree that the wiring diagram should be shown in the listing for this item, so that a potential buyer understands upfront what they are getting. Having said that, I disagree with the reviews stating that this item is "dangerous" because of "incorrect wiring"; it is not wired incorrectly. There were assumptions made in the pre-wiring and if you understand those correctly install the unit, there is no danger.Since the small form factor was a must for me (given available space where it will be installed), I decided to modify the wiring as described below. As an upfront disclosure, I'm used to electronics and have the tools for my needs. The unit comes pre-wired with a negative relay trigger and both relays are triggered together. So, if this assumption fits your needed scenario, you should be able to use it as-is. For me, a positive trigger is needed. Having both relays triggered together is fine for my needs. So, I modified the unit by disconnecting the positive relay trigger from the main relay positive power line it was linked to. Then extended the positive relay trigger line so that the relays can now be triggered either by positive voltage, with the ground side permanently grounded, or vice versa for the opposite. If I needed two independent triggers for the relays, I would have decoupled the two positive relay wires and extended each separately. For my purposes, having them linked is fine.I tested the unit using a 12 volt battery and multi-meter. Tested the fixed supply circuits (blue lines) and each of the relay outputs (yellow lines) wile doing the positive trigger for the relays. This is the scenario I plan to implement. All the functions check out fine; next step is the actual installation in the truck to hook up the new accessories. The firs two attached pictures show my modified unit to get a simultaneous positive relay trigger for both relays. The last picture shows the original wiring diagram (simultaneous negative trigger for both relays) included with the unit.This relay/fuse box is well build and fits my project's needs perfectly, especially the small form factor. My actual score would be 4.5 stars; the half star deduction is for the listing not showing the wiring diagram that is actually included with the product (see last attached picture). This diagram gives prospective buyers a good idea of what this unit entails and what to expect and should be included in the advertisement. If you are handy with electrical "stuff", it is fairly straightforward to modify the unit to suit your needs; if you are unsure, perhaps consult a qualified professional. I went this route since this particular unit is one of the few really small form factor fused double relay units with 4 additional fused circuits, and, after small modification, fits my project's needs. Recommended.
