Special Rain Tracker Installation Notes for this vehicle:

Use the instructions included in the Rain Tracker kit until you get to step 5a. "Make the interface
connections." At that point, use these instrctions along with the diagram that can be printed above.
Return to the general instructions when the interface connections has been completed.

Some models and years may vary slightly in wire colors. Confirm wire colors with service
guide, and/or with 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
Check the Ground-- this can alternatively be BLK, BLK/WHT, or TAN. If you are
not sure you have a good ground, use a chassis ground.

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: gm_lz_c2.veh
