I don’t know. On the diagrams it shows the rear wheel speed sensor and ABS modulator (if you have ABS) going to the combination meter (the gauges) then a bidirectional serial data line to/fm the ECM. And a separate TACHO line from the ECU to the meters.
Book says the ECM sends High oil temp indicator signal, Engine speed signal, MIL signal, and fuel pulse signal to the meters. The meter sends rear wheel speed senson signal to the ECM. All over the serial data line.
The 13’s work differently.
I don’t know why there is a TACHO line if engine speed data comes across the data line.
I’m not really going to be able to help you with customizing the electronics here. Other than whats in the service manual, we have no real data on operation.
