True MODS 12V Automotive Waterproof Fuse Relay Box for 5-Pin Relays

This has been a great addition to my 1997 Tahoe project as an "aftermarket add-ons" relay housing. So far, I've used 3 relay slots for upgrading my upgraded side mirrors to turn the built-in turn signals into turn signal/running lights and 2 relay slots for the door lock actuator polarity swap in the aftermarket remote starter. There's one slot left with no immediate plans and I haven't used any fuse slots yet but I'm sure I'll come up with something lol. Overall, this is a great, easy to use product and it looks right at home in my truck. 10/10 would recommend to any intermediate to advanced DIY guy! Side note: It does come with additional terminal connectors but it still pays to plan all your wiring configurations ahead of time. My "shoot from the hip" method wound up costing me a few of them...

Awesome product, very well built and very nice finish. It comes with a very nice installation hardware. However it does take some serious technical knowledge to install, but that is obvious since you know you will have to run a bunch of different wires through the unit so i would advise you to take to a specialist to get the job done, or just take a weekend to set it up propperly if you are capable, it is fun enough. I installed it on a Toyota LandCruiser 80 Series, made a custom frame for the base and it works like a charm, looks originallish i guess, deffinitely better that it was before. Would totally buy again.

So, it's not a very expensive part so I didn't expect a lot. I broke 2 of the ears off right away. It was my fault, I thought it hinged but it lifts straight off. The connectors are very cheap and pull off the wire very easily. I soldered them in place. They also pull out of the box easy. I used this box for a piece of equipment and the vibration caused the relays to creep out of the socket and my stuff quit working. Luckily it was a test run. I added a 1/2" piece of foam to the lid to hold them in. I added silicone sealant to the back side of the connectors to hold them in place. Overall, I love the concept and the design. The rubber seals appear to work very well. If you can solder and don't mind a little modification, these are worth the money.

This thing is great, I ve used them several times on varioud projects for adding circuts without cutting into harnesses. Use it in conjunction with their power distribution panel and ground blocks. Weather proof and well made. First two I used were perfect, this last one had the retainers missing from the last fuse I went to wire, so I had already wired the entire thing before realizing it, so I only have use of 5 of the 6 relays. Stinks , but too much work to undo. Still a solid unit. would use again.

This is a very nice fuse relay panel. I installed it in my sons 1991 Chevy S10. We have been repairing damage from a front end collision and wanted to add a few electical items to the truck while was out of commission. This gave us capacity for 6 relays and fuses. We mounted the panel to the fire wall of the truck and used 3 of the six relay circuits along with 4 of the fuse positions. One thing that was really helpful and did make a difference in the install was using a pair of weather pack crimpers to crimp, rather than solder, the connections. Once properly crimped with the seals crimped to the terminals they fit nice and securely in the sockets. This relay/fuse panel is really nice. It is well built and well sealed. If there is any suggestion I could make to improve it that would be to include a sticker that could go on the inside of the lid for a legend to identify what fuses power what and what each relay is for.

Quality of the box itself is pretty nice. Very solid plastic, and all the flashings from its mold are all trimmed and sanded. Opening it for the very first time is slightly difficult, the clips hold on tight👌🏽 Green top o-ring and bottom plugs/gaskets should provide a pretty good weather proofing/water resistance. If you do river crossings, I'd still recommend keeping it up higher so that it doesn't get submerged and under pressure just in case. I live in Hawaiʻi, so finding out all the terminals, mounting hardware, and rubber plugs are all heat sealed in plastic to avoid corrosion and draining out of rubber, was a nice surprise.

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.

So, for the price this box is way better than I expected. The quality of the plastic is solid and heavy, and the injection molding is really clean. Comes with Rubber for the base if you decide to flush mount the box, you could possibly Keep the underside sealed if you had a flat enough surface. Comes with extra parts, .. rubber seal plugs, and terminal ends. I don’t know if the plugs were designed to not have the holes go all the way through, but I like it. I can use them inserted in reverse to plug unused holes. Mounting hardware for the box is no joke either, 4 bent mounting brackets, 4 bolts, with 4 flat and 4 locking washers and 4 nylon lock “Nyloc” nuts. Shipped super fast, next day delivery for me, means I can get to work getting my old truck back together quickly. I think this box is going to work out fantastic for my Old Bronco and the relays that just bounce around in the engine compartment.

Decent quality. It's really intended to be mounted in a panel - though they do supply some little legs it can stand on. In combination with some good quality (E.g. Bosch) relays, this is a good option for automotive / marine use.

Good to use and mount

Jai installer cette boîte dans mon bateau pour faire fonctionner quelques circuits, je suis très satisfait, bonne qualité et pas de pièces manquantes, peut-être difficile pour certaines personne sans expérience dans le domaine électricité d'auto.

Just installed it into a piece of equipment we built. Looks great and should hold up to water and prevent corrosion. Will update if I find otherwise.

Quite impressed by the quality of this Vs the price. Was used in drag race car that didn't need the factory wire harness, and used this relay box to run fuel pumps, solenoids and fans. So far it's faultless, will be using these for future projects for sure.
