Buzzing relay means it’s got feedback loop going. Some wiring may be crossed. Or relay may be defective.
As mentioned, might be good to undo some of the changes to use process of elimination to narrow down problem area.
1. put everything back to stock and verify everything works correctly as stock
2. Replace only relay. If it buzzes, then relay is bad. Don’t proceed until you get relay replaced
4. Install LED turn signal. Verify they all work and blink. Turn signal indicator should flash
5. Install diodes to fix turn-indicator flashing
