When installing the sensor, keep the metal back side close to the mounting surface, keep both sides of
the sensor perpendicular to the ground (see Fig 12).
To make sure the sensor is correctly oriented, make sure the wire is exiting from the left/right side of
the sensor specific to their mounting side. The sensor should be installed as shown in the figure below
(The cable can be routed on the top or bottom of the sensor as shown in the figure below, but do not
route the cable in front of the sensor surface) (see Fig 13, Fig 14, Fig 15, Fig 16, Fig 17).

Using a voltage multi-meter, locate the isolated left and isolated right turn signal trigger wires,
commonly found behind the vehicle's left and right tail lamp assemblies.
Once verified, connect the left and right turning signal wires to the appropriate corresponding input
wires of the SDA-BS900 wire harness (see Fig 18, Fig 19, Fig 20). Turn signal inputs of SDA-BS900 is
+12VDC only (not switchable to -12VCD); please check with a voltage multi-meter.
If turn signal lights are
combined with brake lights, then connect the turn signal trigger wires at the front fuse box.
