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 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.

VENTURE VANS
Some Venture Vans (approx 1997-2001) came with a solar reflective windshield
called "Sun Gate", that is not compatible with the Rain Tracker. Look for a
Sun Gate marking on the windshield. These windshields have an antenna grid
built into the windshield, near the rearview mirror.

DEPRESSED PARK SYSTEM
This is a non-depressed park, or standard wiper system. That is, the wipers
do NOT park below the hood when not used. If your vehicle has a depressed park
wiper system, use the instructions for depressed park installation. The
intrucstions can be found here.

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_twm_ndp.veh
