Detroit Diesel DDEC III engine ECMs are ready to connect and operate without any extra
progr amming. The remote throttle is called the Variab le Speed Gov ernor and the signal input
is to ECM terminal D-1.
Interlocking should be accomplished so that the circuit is grounded whenever the remote throttle
should NOT be used. When the circuit is grounded, it is called 525 and when it is operational,
it is called 510.
