Vintage air wiring

[az1970k5]

So the Vintage Air kit calls to connect the red positive wire from the VA harness directly to the positive battery post and the 2 white ground wires to the actual battery negative post. How have some of you done this to make it look clean? I don't really like the idea of having a bunch of different wires coming off the battery itself, besides the actual battery cables. Did you do a junction block before the battery? I figured I could hook up that red positive to the fuse block but Vintage Air says it is very important to connect to the actual battery. I also have the junction block that came stock in my 70. This junction block has a wire from the positive battery cable and from there it has a couple wires branching off to the front end wire harness. Would it be OK to hook up the Vintage Air junction block to the existing block or would it be best to consolidate?
TIA
