ONLINE LED STORE OLS 6 Pack 30A Fuse Relay Switch Harness Set - 12V DC 4-Pin SPST Automotive Relays 14 AWG Hot Wires

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

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

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.
