Disconnect the driver window motor circuit and disconnect the master window switch.
Place the vehicle in the “ignition ON” state using the key or push button ignition/start system.
Turn the vehicle completely off.
Reconnect the window motor circuit and master window switch and verify that the windows still
operate.
If the windows no longer operate normally, the vehicle may require a window programming
procedure after these wires are disconnected. If this is the case, stop the installation and return the
vehicle to its initial condition.
The 535T interrupts the power window circuit in order to control the windows in either direction.
If the vehicle requires a window learn procedure after each time the window circuit is disconnected,
it is not compatible for aftermarket window control modules such as the 535T.
Most vehicles not compatible with the 535T have an OEM comfort closure feature accessible
from the driver door key cylinder. Consult the vehicle owners manual and/or Directed Technical
Support for more information if your vehicle is equipped with an OEM comfort closure feature
that may be used as an alternative to aftermarket window control modules.
NOTE: Window automation is not recommended on vehicles where the window motor is part of a door
module.

This wire provides a ground path for the driver’s window motor down side. Connect this wire to
a good ground point in the vehicle (preferably make a ground in the kick panel that is closest to
the 535T).
