Special Rain Tracker Installation Notes for this vehicle:
Some models and years may vary slightly in wire colors. If possible, confirm

In some, the DK BLU FAST control wire is DK-BLU/WHT directly off the switch,
and changes to DK-BLU at the connector coming from the switch wires.
+12V in accessory or run is not available at the wiper switch-- find
suitable source. (Good choice can be cigarette lighter.) Use 16ga. or larger
10-25amp circuit.
Check the Ground-- this can alternatively be BLK, BLK/WHT, or TAN. If you are
not sure you have a good ground, use a chassis ground.
