Trans Terminal: The Trans terminal is the Transbrake
output. The Trans output is where the Transbrake solenoid
and the 2 Step wire would connect.
Connect one wire from your Transbrake solenoid to
the Trans terminal. Connect the other wire from the
Transbrake solenoid to ground. Also connect the red wire
from a 2 Step or the wire coming from the Launch terminal
on the ignition box to the Trans terminal.
S.F.O. Terminal: Connect the S.F.O. (Selectable Function
Output) to a device that is to function in one of the following
four ways.
1) (S.L.E) Typically a Linkage Throttle Stop to
function as a Starting Line Enhancer to control the engine
RPM at the starting line. If you want to use the S.L.E.
feature, connect one wire from your Linkage Stop solenoid
to the S.L.E. terminal. Connect the other wire from the
Linkage Stop solenoid to a ground.
If you want to use an Air Under the Carb Throttle
Stop as an S.L.E. you can use the S.L.E. output Terminal.
If you want to use an Electric Under the Carb Throttle Stop
as an S.L.E. you must wire in an external relay to handle the
higher current of the Electric Throttle stop.
2) (Timer 2) A device to be controlled by the second
four-Stage timer. Depending on what is being controlled by
Timer 2 the Throttle mode can be set so the output will
supply or remove 12 Volts. The Timer output cannot supply
ground. One wire from the device needs to be connected to
the S.F.O. terminal and the other wire from the device needs
to be connected to ground.
Note: If the device to be controlled needs Ground, instead
of +12 Volts, an additional relay will need to be
wired between the Mega 475 and the device, page 61.
