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, except ground, 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 CHASSIS GROUND
Find a suitable screw or bolt on the metal chassis of the vehicle to use as the
Rain Tracker ground. Scrape away paint as needed for a good connection.
Use a multi-meter to verify that the ground connection is at most a few ohms.
The cigarette lighter can also be a good alternate for ground and/or power.

+12V CONNECTION
Some years may have +12V - RED/WHT. Also, there may not be a suitable
+12V from the switch. The cigarette lighter is generally a good choice for +12V.

SLOW CONNECTION
On the 911, SLOW may be BLK/PPL. Verify with multimeter.

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

The Rain Tracker wiper control system works in parallel with the existing wiper system, so the existing manual control modes are not affected. This page generated by vehicle data file name: porsche_911_82-89.veh
