- For the left rear parking lamp, turn signal, side marker lamp, and the rear license plate the Z1 circuit grounding point is in the left rear wheel well.
- For the right rear parking lamp, turn signal and side marker lamp, the Z1 circuit grounding point is in the right rear wheel well.
- Circuit L7 also feeds the radio, if equipped.
- When the headlamp switch is in the PARK or ON position, the dimmer circuit, F33, connects to circuit E1.
