I'm glad this project is catching on! I have gathered some more supplies.I wish I can edit the my first post so that all of the information is in the one place. But looks like I'll just have to post as I go and it shouldn't be too hard to track on this thread.As I mentioned, this is my first time building a relay/fuse box so there was a bit of a learning curve. I wanted to post my found resources on top of the progress photos just in case it could help anyone new to electrical work, but wanting to build their own.NOTE: I would suggest you do additional research to fill in any gaps that I might not cover here. But feel free to ask me any questions and I'll do my best to answer them.Some basics:My build:Planning and more planning is key to a successful relay box. I purchased components that are rated at 30-40amps, so I will only add accessories within that capacity. I plan to install horns, lights, fans, etc. Not larger things like winches or air compressors, etc. since they'll need their own heavier duty relays, wires, and connectors.As far as laying the components out, I want to tuck everything into a small enclosure that can be mounted under the hood and sit on top of the battery. I found a waterproof camping box yesterday but I have not decided if I wanted to go with it. I may just fabricate my own enclosure.
