Bought the car with a standard head unit, want a new one so I bought a pioneer MVH-S420BT, a new harness and a piggy back because I'm aware it won't turn on without it. My question is, what amp fuse do I put in the piggy, and using the diagram I'm unsure if I can just use a meter and find an ignition live, or use the current radio hole.
Forgive my naivety, first time having to mess around with any of it as every other car I've had has been plug and play.
