Special Rain Tracker Installation Notes for this vehicle:
PLEASE NOTE: Before installing check that the wire colors exist for your vehicle.
One customer tried installing the RT-50, with these instructions, onto an 2007 Silverado
and found no matiching colors. If you see that none or just one of the colors exist,
compare it to the 2007 Uplander instructions and use that if needed.
+12V in accessory or run is not available at the wiper switch-- find
suitable source. (The cigarette lighter can be a good choice.)
Alternative: YEL wire going to REAR wiper switch is hot in accessory or
run for many.
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.
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.
