Installing Additional Car Horn

Hi ka-DIYs!
I attempted to install an additional car horn to a Hyundai i10 model. Things I used are as follow:
1) Additional car horn
2) 12V 30A 5-pin Relay set
3) Fuse with box/housing
4) Electrical wires and tape
Some things to take note:
1) Some car horn sockets vary. Check what sockets is compatible to your vehicle.
2) There are different types of relays. I used the 5-pin relay.
3) Have a multi-tester handy as you will need to identify positive wire of the stock car horn wiring. Some cars have color coded wires. A positive wire usually is color RED.
I hope you enjoy watching this video.
This is my attempt to DIY.
I am not an expert, seek opinion to a professional when needed.
Installing additional car horn took me 1 hour to complete. Make sure you tighten back the bolts and secure the wires
