True Mods Waterproof 12V Fuse Relay Box Block Kit w/Pre-Wired Harness [12 & 16AWG] 6 Gang Bosch Style 5Pin 30A/40A Universal Relay & Fuse Panel for DC Auto Automotive Vehicle Car Marine Boat Jeep UTV

It was too big to fit under the hood. Too much stuff in the way. I wish it had fit, it’s a good looking unit. Well made and heavy gage wire. If they could make a 2 or 4 relay box I’d buy it.

I bought a kit since I prefer to solder connectors, and I wanted to use some heavier gauge wire on a couple of the power and load sides. I also didn't need access to any of the normally closed connections. The kit came with everything except the wire, and included some spares for just about everything. A collection of fuses.were also included.The box is rugged and well made. The seals all around are good quality, and the wire holes are closed before punching a wire through. The relay bottom seals are properly sized for 16 gauge switch wires, and 14 gauge power wires. And the fuse seals are for 14 gauge. The relays can be wired for normally open, or normally closed (or both).It took several evenings to get everything soldered and wired neatly. I recommend the pre-wired version if you're not patient, comfortable with wiring, or if you don't have the tools. And considering the wire alone will cost $20, the pre-wired kit amounts to free labor.Overall, this is a very good quality kit with everything but the wire included.

I bought this to upgrade a Ford f100. I am in the process of adding relays for a dual electric fan setup and headlight relays. Right now I only will be using 4 out of the 6 available fuses and relays. I was a little worried when I read the review by someone saying that they had a hundred dollar crimper and something called f dies that they couldn't get to crimp the terminals properly. I decided to risk it and try it anyway. I have a crimper I bought on sale for 9.99 at my local big box store (the crimper in the photo). After drawing out my wiring diagram I crimped one as a test and could not pull it apart, no matter how hard I tried. I guess $10 crimpers must be better than the $100 version with seperate dies. I did buy the kit instead of just the box because I was unsure if the box only version would come with the seals. The fuses are super cheap and flimsy. I probably will not use them since they are just normal automotive fuses. The relays seem ok, I will use them if they work. I plan on adding a few more pictures once I get everything installed. I do not like the metal mounting brackets so made a flush mount spacer for the wiring out of some expanded PVC and a CNC router. But that was just because of aesthetics, I'm sure sure the included brackets would have worked as intended. A few reviews mentioned the cover breaking, I put it on and took it off a few times and haven't had any problems, so fingers crossed I won't have the same issues. Overall I think this is going to be a great upgrade to an old truck that didn't use relays for anything.Update: I do intend on adding a few more pictures of the completed installation, unfortunately I ran out of warm weather and now the old truck is tucked safely away in the barn until spring. Once it warms up I will post more pictures. But I am still completely impressed with the relay block, from my original post in June until the weather turned ugly in December I have had no problems with anything I wired through the block.

It took a lot of work, but the end product was well worth it. While the assembly instructions lack a great deal, with a little trial, error & testing, it actually goes together fairly easily. (Don't forget to install the silicone seals prior to terminating both end of your wires.)This panel would greatly benefit from additional fuse locations and better terminal containment.Definitely worth the price and hard work!!!

haven’t installed yet, but very well-made

REbuilding an old CJ5 and upgrading all electronics. I wanted something that is tough, waterproof, and performs. As others mention, the build quality is great. Glad I went with the harness version as the wires are all sealed very well. I love that this has individual power leads and also has individual wires for each relay pin so you can decide to wire using power in to trigger or use a ground wire to trigger. Really happy with this purchase.

I found this to be very well constructed. Base is of heavy plastic. The wires nicely organized and labeled. Easy to install, but you must have a basic understanding of automotive wiring and relays. If you have that, you will be golden. Instructions are also very good.

Works really well until the fuse holder rusts out. The lid doesn't close tight enough to be water tight. Drill some drain holes in the bottom and use a lot of dielectric grease and it will be fine.
