Is a factory fuse block a requirement to build a proper standalone LS1 wire harness? I have a factory van harness, but I do not have the factory van fuse block. It is okay (or ideal) to build my own (new) fuse block like the one pictured below? Would doing that make it okay or acceptable to NOT install the factory fuse block? I guess I am having trouble wrapping my head around the ideal of what the final standalone wire harness needs in terms of fuse protection. I plan on omitting unneeded stuff from the engine and only running required things like fuel pump relay, O2 sensors, MAF, injectors, coils, etc. I’d assume a fuse block of some kind would be needed, but I just don't know if this one below is sufficient for the standalone configuration. Thoughts?
