This unit, #711, will produce the exhaust chuff sounds. Input J4 would
be hard wired to J2 gray as page 2 explains. Inputs for J5 would not be
connected. If using the LocoMatic™ Controller you would connect pin 1
of J3 on this unit to the upper unit as shown on page 3 and 4. You will
also have to connect the choke as shown on those pages.
