Has anyone got an ECU wiring diagram they could e-mail me?

 

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

 

Thank you very much, hopefully that should do it. I'll let you know how I get on.

Cheers

 

what about the 02 sensor??
I need to know where the pin is and what wire it is so i can hook up my a/f guage..
