2004 Honda Accord Instrument Cluster Wiring
 

Hello,
I have an instrument cluster taken from a 2004 Honda Accord and am trying to power it outside of the car. Does anyone have a pinout or wiring diagram for the connector that goes in to the cluster?

It is a pretty "scattered in the service manual so I don't have all of it in one place.

Is there a specific circuit in the cluster you are trying to power up?

For around $27 you can buy a very good service manual for your car.

I'm not sure what you're hoping to do with it. The system is not just simply wire a few wires.

The gauges and indicators are part of the MICU (Multiplex Integrated Control Unit) system. Some indicators are controlled by conditions in their specific systems. Information for these indicators is communicated from control unit-to-control unit across the multiplex system.

The following indicators are multiplex communicated to the gauge control module:

•  Charging System Indicator
•  DRL Indicator
•  High Beam Indicator
•  Lights On Indicator
•  Maintenance Required Indicator
•  MIL Indicator
•  Seat Belt Reminder Indicator
•  Security Indicator

In addition, there are individual systems information that go to the gauge control module such as:

• Engine Coolant Temperature Gauge
• Fuel Gauge and Low Fuel Indicator
• 
  Speedometer
• Tachometer

The ECT gauge, speedometer, and tachometer is communicated from various sensors through the ECM/PCM.
