True MODS 6 Pack Bosch Style 4-Pin 12V Fused Relay Kit SPST 30 Amp

I like this product. The fuse is easy to see and check. Easy to wire, works great

I bought few of these 30amps with fuses 30amps with out fuses, 60 and 80 amps to install in my drag truck making it a street weekend truck. Cheaper buying them here than going to local parts store. I have 4 ground wires going to the body in different location. Power items - dual fans, water pump, fuel pump, transmission cooler mounted under the truck. All is on a ground wire coming off grounded wire - not like most people will just ground a item to the body. I like to make sure I have a very good ground. Also like to make sure when the truck is running at idle I have14 volts inside the truck cab at the ignition switch and power going out of it. The switches work for me no problem with anyUpdate 10/26/2019no problems with the relays. I have not blown a fuse yet. Some people could be having problems, Not a good ground source, wiring gauge to small, Amp draw on start up exceed 30 amps on. - On fans amp draw can be high when 1st turn on. All power source should be check amp draw on start up so you can match the relay to amps being used. I have 4 ground wiring. I have dual fans 2800 cfm each, fuel pump 14gp, water pump, trans fan cooler, My fans on start up both pull 32 to 35 amps then runs at about 22amps - So my relays on the fans I'm using 60/80 amps. Everything els I'm using 30amp relays. at idle with these on fans both, fuel pump, water pump, trans cooler fan is 30 amp relay my amp draw is 68 amps. For some of the people having problems I hope this help. My wiring gauge 8 on the front fans, 10 on the rest. I'm not using the the wiring that came with it.

Works great!

These relays, sockets and fuses are a terrific way to power up and protect a component with the least amount of wiring possible. The big plus for me was having the fuse contained within the assembly so a separate fuse didn't have to be wired into the circuit and a customer may not know where to look for it in the event of a failure. This feature is also the one detraction I have about these parts. I thought the fuse was part of the socket assembly so the relay could be changed independently. When I received the order I saw that the fuse is part of the relay body itself, not the socket, so one needs to keep a similar relay (with fuse attached) in the car as a spare in case it ever goes bad, or risk running with an un-fused circuit if another manufacturers relay is swapped out.For ease of finding the correct fuse I give these relays an A+, but for convenience of being able to find a replacement part if one isn't on hand I have to give them a D since they'd have to be re-ordered from the online store.

Only needed one, but bought these because of the value and fit. Easy to install.

… works perfect.. quality made.. . fuse should have snap on dust cover.. installed on 2 Buick lasabre’s .. to keep radiator cooling fan running (slow speed) all time when ignition key on.. hot wired into main fuse panel under hood .. keeps coolant at 195-200 all time.. due to Buick design fan originally only comes on when .. a/c on.. or .. when coolant reaches 235-238 deg.. (spec ) which is frequent in stop and go traffic. .. .. that’s an engine killer.. ‘o’ stars for GM engineering.. I recommend..

It saves needing to wire in an inline fuse and relay box so these clean up the wiring some. I like that it comes with a harness for each relay so I can unplug the whole relay and wire it easier. They’re modular so you can stack them side by side for a cleaner look. Only downside is the little mounting hole on the top is very brittle. I screwed it into my car and it snapped right off so I superglued and wrapped a zip tie around the relay to hold the mount on sturdier.

I like that the fuse is already part of the relay housing. I don't have to have an ugly inline fuse. I used these to connect light bars and light pods on my various vehicles. they work like a charm and I would buy them again if I needed to. If I didn't want the accessory functional, I just have to pull the fuse on the top, instead of digging through a bundle of wires. Yay!

Good product

Be very very careful wired incorrectly, i had to pry the wires out the connector and switch them around to colour match correctly as shown in picture, manufacturer issue
