DAIERTEK12V Fuse and Relay Box 6 Slots Relay Block 6 Slots ATC/ATO Fuse and Relay Block with Relay Universal Waterproof Fuse and Relay Box Kit for Automotive Car Truck Marine Boat

You won’t be impressed by the quality, as the plastic isn’t very thick and it certainly isn’t water proof. However, for the price I think it’s great. I mounted both the box and a 250 amp bus bar (also from Amazon) to a piece of stainless sheet metal and made a functional power distribution box. It will keep the mud and other debris out and is far better than mounting exposed relays and inline fuses everywhere.I purchased the wire yourself version and as others have said there are just enough connectors for all slots, so take your time. The orientation of the connectors is important as well. They must engage the plastic prong in the slot otherwise, they will push out the bottom when you put in a fuse or relay. If inserted properly the connectors remain secure.Lastly the fuses that come with the boxes are suspect. I quickly blew two of the included 30 amp fuses after getting it all set up. Wasted about an hour rechecking all the wiring (thinking I messed up), before going to autozone and purchasing some more 30ampFuses. With the new fuses everything worked as advertised.The supplied 30 amp fuses seemed to blow around 25 amps. No problems with the relays so far.Bottom line: It enables a tidy wiring solution, provides some protection and is inexpensive. I would buy another.

Received this product, and spent a few days doing wiring, crimping connectors, pinning the relay box and fuse panel. Went to install relays and they push all the pins out the back. Had to flip the box over and install every single terminal individually into the pins. The pins provided with the kit are ok quality, but you dont get any extras. Been a mechanic for 20 years, and never had this much trouble assembling a relay/fuse panel. I guess you get what you pay for.After a while i was able to get all the relays installed with all the terminals properly seated, but if I ever have to remove a relay to test or replace, ill have to remove the entire panel, flip it over, remove the rear cover and put the pins in the relays manually one by one.This relay panel does a nice job of cleaning up wires for multiple accessories but there exist much better quality relay panels that wont require you to disassemble the relay box every time you want to replace a blown fuse or a faulty relay

For the price it is grand, extra pins and fuses, relays seem substantial, plastic box wish bottom just a tad deeper but certainly OK... BUTAll relays and slots the same for 6 Bosch style relays not for 1 RTT7121 4 pin relay and 5 Bosch - not a real problem BUT leaves the "buy" and the directions/images inconsistent with reality. Also the box came configured inconsistent with the directions - again not a real problem to me.But one must know fundamentals, think , and adjust before wiring - do not blindly follow directions.NOT real problems, and am very satisfied, but I do have cautions. For the price it is grand and on that basis I give it 5 stars.

Finally I got to work on the box and to my surprise the terminals are missing. The relay terminals are no Biggy, but I have no fuse terminals. Now I have to run around to get some, hoping they will fit. I did not get for what I paid for, the biggest problem being the time. I need to finish the box wiring.

First one I got was broke in shipping Amazon replaced new one worked good with ls swap harnesses
