Sorry, rushing to get this done before dark...
so I disconnected the 2 front horns and pulled the horn fuse from the box on the LHS passenger well. Disconnected the battery and turned up the voltage on the battery cables with a variable power supply, and at around 7V I hear some clicking near the engine front (?) (relay?) and there was a light honking sound. I look around and I see what looks like a small horn on the RHS fenderwell near the big resistor for the fuel pump. It says Denso on it and looks OEM. What is that for? Could that possibly be for an OEM alarm? I don't recall there was such a thing. Was there? And where is that relay?
