Trailer Tow Wiring
WARNING: This page is about a different car, the 2012 RAM Pickup and 2012 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
In addition to the trailer tow wiring provisions, the TIPM in all vehicles includes dedicated trailer tow battery, trailer tow park lamp, and both right and left trailer tow stop/turn feed output circuits. When the TIPM receives the appropriate inputs for normal park, turn signal, hazard warning or brake lamp operation, it responds by providing battery voltage through the appropriate trailer tow wiring feed circuits to synchronize the illumination and flash rate of the trailer park, brake and turn signal lamps with those of the tow vehicle.
