Special Rain Tracker Installation Notes for this vehicle:
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.
For wiper systems w/o intermittent the slow may be WHT. with respect to
where the wires are pulled. Should be BRN/WHT if directly off switch.
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.)
