Special Rain Tracker Installation Notes for this vehicle:

Write the wire colors of the vehicle on the HSS drawing, and follow that
when you wire up the Rain Tracker. Use the factory drawing as a reference
to help you find the wires. Some models and years may vary slightly in wire colors.
Factory drawings can be wrong, so, confirm wire colors with a multimeter.

All wiper system wires are available at the wiper switch. They can usually be accessed
by removing one or two access panels (Kick Panels) and, possibly, the shrouds surrounding the
steering column.

SLOW Wiper Motor Winding wire color varies between year models and may be BLK/GRN
on some models of the 5000

The RT-40A does not utilize the FAST windings of the wiper motor. Please disregard any references
to FAST that appear in these instructions.
