would this be enough?

More. A bit more if you upgrade the materials and piece it out. Plus you need cable retainers, terminal ends, heat shrink, the switch...

what gauge wire do you recommend then moper? Mullinax says atleast 0 ga for ground and hot and atleast 4ga for alternator...is that enough? Taylor also sells a relocation kit that is the same length and stuff, but comes with 1ga welders cable...let me know what you think
