Horns are normally wired so that they'll work all of the time. Sounds to me
like you have a pinched or broken horn wire somewhere near the turn signal
assembly that gets grounded when you turn the wheel or mess with the turn
signal lever. It could well be the case if the circuit was designed to
switch the ground rather than the 12 volt/power side.
You can switch either to control a circuit. Although it's more common in
domestic designs to switch the power, Datsun designed many of the circuits
in these cars, the 510s and Z-Cars to switch the ground.
Isn't electricity fun! :>)
