I have bought a pair of Fiamm snail air horns to replace the standard Fiat squeeky horn. I am ready to fit them and have read the Fiamm instructions. There lies my first quandry. There are 2 ways to wire the horns dependent on how the Fiat is wired. Does the horn button when pressed complete the circuit to earth or does it complete the circuit to the positive. Depending on the answer the wiring of the relay is different.
Is this a convoluted way of asking if the vehicle is negative earthed or positive? To my mind positive earthing went out before I started driving back in the 1960's! If it is then I know that the Fiat is negative earthed. If their question is not this then I haven't a clue!
Can anyone advise how Fiat do it?
As you can probably tell, sparky stuff is not my forte!
