Brake
Body
Remove the two black wires from the old brake body from their wirenuts
(attached to the red and black wires). Install the new brake body wires in the
same manner as the old ones were removed. Either black brake wire may be
connected to either the red or black wires - polarity is not important. Be sure not
to reverse the wiring of the diode. (POLARITY DOES MATTER ON THE
DIODE). Be sure wire nut setscrews are secure. Refer to Figure 5 for details of
this step.
