I'm trying to set up another horn in my car, and I have a few questions. Firstly do I connect the power supply of the relay (terminal 30) to my cars fusebox or the batterys postive terminal? Also how would I set it up so that I have it connected to a switch that selects between my old horn and new horn. Pic related

Terminal 30 should go where ever it's easiest to get voltage. But, I would find a switched fuse block not being used. Either you have a second switch or have a 3 way switch so you can use your steering wheel's default horn location.

You'll need a switch between either ground or 12v that chooses either old horn or new horn. Or both. Or none. You'll figure it out.
>>
You need separate relays and switches for each horn.

Are those the two horns you want to select in your pic? I would suggest using a seperate relay for each one. Connect both terminal 30s to the fuse. Connect each horn as shown in your pic. But install a SPDT toggle switch between your horn switch and each relay's terminal 86. That way, the selector switch will only have to carry the low relay coil current.
