Does the starter relay 12v battery post need 12v?

I modified my existing harness when I built my Hardtop. Doesn't mean it's right! lol, had a similar Delima so I added this.I used some fusible links as well that I know I will get critisized for but hey, It's my car and I did everthing myself. Maybe someday I revamp it but it's been about 10 years now. (yellow arrow unrelated)
