Steve,
Your problem may be the horns, but I think it's something else.
Post CF-1 cars used a solenoid valve mounted below the charcoal canister to
prevent 'run-on' after engine shut down. This valve is wired into the oil
pressure switch (3 wire switch) such that the valve becomes energized for the
few
seconds following shut down until the oil pressure bleeds down to zero. Check
the wiring on your switch - the valve is controlled at the pressure switch by
grounding the white/purple wire. Check your connections that the terminal isn't
bent over touching the black ground wire (a common occurrence is to mash these
up
when changing a canister oil filter). Otherwise, your connections being good,
check the function of the switch with a multimeter or by observing the oil lamp
on the dash with the key in the 'run' position.
Good luck!
