Like the one that's available in the wiring diagrams of the service manual available on my site? Or are you looking for a circuit diagram of the ECU itself?

What I need to know is which wire is the speedo signal wire? Do you know? I'm wiring in a speedo converter from KPH to MPH on a JAP import.

What I have may be wired completely different from what you have. On a US '93, there are two wires comes from the speedo sensor to the speedometer.

The connector with the wires on it is a 12 pin connector.
The colors are:
Y/W - speedo sensor
BR
Y/R - speedo sensor
BR/W
G/R
Y/L
R/G
L
and optionally V/W
three pins will be empty, possibly the V/W one too
