Hello all, I’m a 17 yo with a dream. I’m trying to pre-plan and make a wiring diagram for my setup. I have a 2018 Chevy Malibu 2.0 premier that I plan on putting the flat law 3 liter, the electronic drain for it, the oogah horn, and a musical horn. I want all the horns on different momentary switches in an overhead console. I also want to put the compressor on a switch to be able to turn it off if I just don’t want it to run, but I want it to also turn off when I turn the car off. I also want to be able to drain the tank from inside my car on another switch on the console. That is not the problem though. I want to use a fuse block that also has built-in relays because I think it will make wiring a lot easier. It’s Amazon.com: WUPP 12V Fuse Block with Relay, Automotive 6 Circuits Fuse and Relay Box With ACC Interface, Universal Fuse Block and Relay Kit for Cars Trucks Marine Boat : Automotive on Amazon. No with that said will I still need to use the 40 amp relays that come with the Train horns compressor, musical horns, and the oogah horn? If so how do I wire that up?
Never mind i figured it out and am not using that relay block because it isn’t a high enough amp.
