the timer circuit and go directly to the 
switch. Use this connection when 
going to a 3
rdparty timer or when the 
timer circuit is not needed. The 
orange, black, yellow, blue, and red 
wires would not be used if you 
connect to the green / white bypass.
IMPORTANT: If the Green and White wires are not used, cut wires to avoid a possible malfunction.
