On my 4BD1T, I have three mechanical cables that go to the injection pump: first is from the accelerator pedal and controls the fuel quantity, the second comes from the electric servo motor and activates the fuel shutoff lever to stop the engine, and the third, the mystery cable, also comes from the electric servo motor and loops behind the injection pump and rotates a shaft on the injection pump that is between the pump and the engine block. What is the purpose of this cable? Both my 1985 and 1989 4BD1T engines have it while the '92 4BD2T does not. There is no mention of it in the FSM.
What is it?
