All wires except +12V are available coming from the wiper

two access panels (Kick Panels.) For Rain Tracker power (+12V), locate a
source of power hot in accessory or run.(min.16 ga/ 10A circuit) The
Cigarette lighter is often a good +12V source.
Some models and years may vary slightly in wire colors. If possible, confirm
