True MODS 6 Pack 4-Pin 12V Bosch Style Fused Relay Switch Kit [Interlocking Harness Socket Holder] [14 AWG Hot Wires] [SPST] [30 Amp] 12 Volt Automotive relays with Fuse for Auto Cars

All pins and sockets were straight and tight. All leads had insulation separated at last 1/2 inch or so to ease installation. I used these relays to replace OEM relays and inline fuses in an off road LED lighting installation on an ATV. Very limited space available for installation. With an integrated fuse, these were smaller than the OEM relay with separate inline fuses, thereby reducing the overall space needed, allowing for a smaller electrical junction box to house them. These were every bit the quality I have come to expect from Bosch after 40 or so years in the auto repair business. They function fine and make almost no noise when activated. I am satisfied with this product.

Great deal, great quality. So far so good, nice heavy wire, seems solid materials. Time and heat will dictate ACTUAL build quality though. Went with the Bosch version over the less costly types, no sense in skimping on a part that can fail at a time and place you REALLY dont need

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 any Update 10/26/2019 no 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.

Bought these relays and used them for over a year. Downside is there is no diode for negative voltage spikes when turning off the relay due to the induced flyback voltage once the relay power is disengaged. This isn't good for your electronics long term. Would but more of these i they had a diode. Would also like these in 40amp continuous power

Used these mainly because I like how they attach to eachother for easy mounting and able to keep wiring clean. Having the fuse built into the relay is a cool feature. Wire is cca for those who are wondering. I have these powering low amp products( led lighting, starlight) and have no issues. Very happy with these relays.

Works great!

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!
