True MODS 12V Automotive Waterproof 5-Pin Prewired Relay Fuse Box Block Kit

the mounting feet make for a lot of options on uneven surfaces under the hood and the box is super sturdy and watertight. Not sure why is needs 6 heavy gauge power and ground wires instead of just a single 4 AWS of each. That makes for a lot of mass coming out (6 x 5 heavy wires) but it sure works nicely.

Great little power distribution block. The relays have been performing flawlessly running dual electric cooling fans and my electric fuel pump. I also run all my accessory lights off it. The wiring was simple to understand and install. Being able to wire each relay independently was what I needed to run a couple in a negative power on setup.

Fantastic kit. Was able to wire up several accessories on my hot rod including electric fans for radiator and transmission cooler, electric water pump, electric fuel pump and still had a few slots left. Also, there’s plenty of wire to tie into so you’re never in an awkward spot trying to solder or heat shrink. Excellent quality as well. Will most likely buy another in the future. Highly recommend.

Nicely built box that incorporates all your fuses and relays into one convenient package. Comes with a cover and mounting hardware. My one gripe with it is that the cluster of wires could probably be "cleaned up" better to exit the box more orderly to help with not being such a hinderance in mounting the box to a surface.

This is a great relay box. I gave a 4 rating because instructions & the items supplied in the cardboard box don't agree. Here's what was included in my purchase on 5/25/25. A black plastic relay box having a lid with o-ring gasket. The box has six 30/40 amp relays installed. Each relay is feed by an 11 inch long wire. Wire size TO relay contacts is 12 AWG. Wire FROM relay contacts is 12 AWG and is 11 inches long. Wire to and from relay coil is 16 AWG and 11 inches long. Included are 6 blade fuses installed in the relay box plus 6 blade fuses packaged separately. Total of four 10 amp fuses; four 20 amp; two 25 amp and two 35 amp. There is a single lug terminal (0.320 hole) connected to six 12 AWG wires which are 6 inches long. There are four non-stainless bracket mounts with 4 sets of stainless bolts, flat washers and nylon locknuts. There are 6 butt connectors for 12 AWG wire. The instructions are readable and very understandable. Each red power supply wire going to the box is labeled for the relay it feeds. Each relay has 5 wires leaving and each group of 5 is labeled as to the associated relay. Note - the clips holding the cover are difficult to release.

I was extremely surprised at how high the quality of this item is and as far as I can tell, it will definitely be able to handle the elements inside the engine compartment, the wiring used is definitely high-quality, and this item is a must have for those looking to build accessories for their vehicles requiring fused relays in order to run lower amperage wire through the firewall to their switches.

Very well made fused relay block. Unfortunately there was no place to mount for my application. I would most certainly buy again if the application were different.

Excelente producto. Llegó muy rápido.

The Small clips that hold top in place break very easy Very well made. Maybe they can replace the top without sending whole unit back. if they replace will change to 5 stars.
