Headlight Relay Upgarde Question

[Already Gone]

I am doing the headlight relay upgrade on my truck and have everything figured out. It says to hook the 12 gauge wire with inline fuse or breaker to the positive battery post. My question is, instead of running the wire to the positive battery post could I use the junction block seeing the big red wire comes from the positive post to the junction block. It'll make for a neater job when I run the 12 gauge wire back throught the wire loom that goes across te top of the rad. I'm thinking it should be okay but thought I'd ask the electrical gurus..
