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.

The FAST and SLOW 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. Locate +12V and GND.

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.

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.

INTERFACE
These instructions are for vheicles that DO NOT have depressed park. That is, when the wipers are
off, they DO NOT move to a lower position below the hood. Use depressed park intructions if your
vehicle has a depressed park system.

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: ford_twm_nd_c1.veh
