Understanding the Wiring Diagram for Grote Turn Signal Switch
Diagram Overview
A typical Grote turn signal switch wiring diagram visually represents the electrical connections from the switch to all related components. It uses standardized symbols and color codes to depict wires, switches, bulbs, and relays.
Color Codes and Terminal Labels
While specific wiring color codes can vary, common conventions include:
- Red: Power supply
- Brown/Black: Ground connections
- Yellow/Orange: Turn signal circuits
- Blue: Hazard light circuit
- Green: Indicator lights
Terminal labels on the switch might include:
- Input Power (B+ or 12V)
- Left Turn Output
- Right Turn Output
- Hazard Output
- Ground (GND)
- Indicator Light Feed
Typical Wiring Path
1. Power flows from the fuse box to the switch terminal designated for power.
2. When the turn signal lever is activated left or right, the switch routes power to the respective turn signal circuit.
3. The flasher relay modulates the current, causing the bulbs to blink.
4. Indicator lights on the dashboard illuminate corresponding to active signals.
5. Ground connections complete the circuit, allowing current to flow properly.

Step-by-Step Guide to the Grote Turn Signal Switch Wiring Diagram
1. Identifying the Switch Terminals
Before wiring, identify all terminals on the switch. The switch usually has multiple terminals for:
- Power input
- Left turn output
- Right turn output
- Hazard output
- Ground
Consult the specific wiring diagram or service manual for your vehicle or switch model to identify terminal labels.
2. Connecting Power Supply
- Connect the power terminal on the switch to the vehicle's 12V battery via a fuse.
- Ensure the connection is secure and insulated.
3. Wiring the Turn Signal Circuits
- Connect the left turn output terminal to the left front and rear turn signal bulbs.
- Connect the right turn output terminal to the right front and rear turn signal bulbs.
- Use appropriate wiring gauges to handle current loads.
4. Installing the Flasher Relay
- Connect the relay to the switch's output terminals.
- Ensure the relay is properly grounded.
- The relay controls the blinking pattern.
5. Connecting Indicator Lights
- Wire the indicator lights on the dashboard to the corresponding output terminals.
- These lights inform the driver which signals are active.
6. Hazard Light Wiring
- Connect the hazard switch to the hazard output terminal on the switch.
- When activated, the hazard system lights all turn signals simultaneously.
7. Grounding
- Connect all ground terminals to a solid chassis ground.
- Proper grounding is critical to prevent flickering or non-functioning signals.
