Special Rain Tracker Installation Notes for this vehicle:
Note: The fast slow and ground are all accessable from the switch relay,
however the +12v is located out of the T.A.C.U. Which can be found by following
any of the green wires, and has been noted to be under the drivers seat in some instances
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.
This is a ground side switching system.
All wires except +12V are available coming from the wiper
switch. They can usually be accessed by removing one or
two access panels (Kick Panels.) It is almost never necessary
to remove the steering wheel.
For Rain Tracker power (+12V), locate a source of power
hot in accessory or run. 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 colors may vary by model year from the vehicle illustrated.
Use a test-lamp or multi-meter to confirm you have the right wires.
