Special Rain Tracker Installation Notes for this vehicle:
NOTE: The SLOW wire on the Crown Victoria, Cougar and Capri may be WHT.
NOTE: If this configuration does not work, the Rain Tracker may be installed
directly at the wiper motor teminals. If this is the case and you would like
to install it this way, the FAST wire may be DK-BLU/ORN or DK-BLU and SLOW
may be BRN/WHT or WHT all at the mototr terminals. Verify operation with a
multimeter.
Special note: The slow switch is not directly tied to the slow winding,
however it is tied to a relay that in turn supplies power to the slow
winding. This does not affect the implementaion of HSS.
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.
FIND CHASSIS GROUND
Find a suitable screw or bolt on the metal chassis of the
vehicle for the Rain Tracker ground. Be sure to scrape
away paint as needed for a good connection. If possible,
check the ground connection with a multi-meter. (It should
be at most a couple of ohms.) An alternative source for
ground is the cigarette lighter. (This can also be an alternative
source of +12V power for some applications as well.)
