Special Rain Tracker Installation Notes for this vehicle:

Write the wire colors of the vehicle on the GSS 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, except +12V, 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.

FIND +12V
For Rain Tracker power (+12V), locate a source of power hot in accessory
or run. Power source should be min. 12-16ga. wire on a 15-25A circuit. This
can be one of the +12V sources as shown on the diagram, or some other accessory
source. The cigarette lighter is often a good +12V source.

WIRE CONNECTIONS
On some the years of the Tooper, FAST may be YEL and SLOW may be WHT.
1982-1989 I-Mark, SLOW - BLU/WHT

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