I'm relocating the under hood fuse box to the trunk of my 99 civic because the previous owner had it placed in the glove box poorly. I've extended all the wires running to the fuse box with 18 and 10 gauge wire. Will there be any resistance because of the length of wire? Do you think all the extra wiring will cause interference with my sound system. Also I want to consolidate some of the wires. I saw in a thread a connecter where two 4g wires went in one side and 1 came out of the other and now I can't find it. Does anyone know what it's called or where I can get one?
