Tan wire is the heat sensor,
I'd say you are getting a no oil warning.
Check the sensor sender in the oil tank.

Temporarily disconnect TAN wire from horn. If it continues to sound, the horn is faulty. If it stops sounding, then start disconnecting the sensor wires at the engine.

Sensor wires are: Tan wires leading to oil tank, wires leading to (2) overheat sensors in the cylinder heads, wires (round electrical plug) leading to VRO pump, and wire leading to fuel restriction vacuum switch.

The exception to one of these sensors being faulty is that the Tan wire between the warning horn and the engine is shorted to ground at some point.
