One problem related to wiring has been reported for the 1998 Plymouth Grand Voyager. The most recently reported issues are listed below.
Break pedal stop light switch. The wire harness moves every time you step on the pedal, thus making the wires break. When the wire breaks the stop lights don't work and could and almost lead to a few rear end crashes I had. Wires replaced and had pedal and harness to configure not to move when the break pedal pressed.
