ECU pinouts sorted by colours?
Hello i have a 2000 Impreza that had a Autronic SM4 installed, im about to change to link now
i have found the pinouts here
http://www.brdevelopments.com/docs/MY99ecu.pdf
But my problem is that the connectors has ben removed so all i can do now is to go by the colours of the OEM lead, Does anyone have a page where i can see what cable runts to what by their colours? as they are all unique i assume this is a way to do it aswell? or do i have to measure every cable?
Best regards

Most stuff sorted out now but i have one thing that i wonder, i have 2 wires that controlls the Fans (one Green and Red) thats supposed to sit at "A13" and a Red and Blue at "A4"
But i also have 4 Green and Red (a bit thicker) wires that goes into 2 pins and i cant identify them, they look like this
Any clue what those are?

looking at the wiring diagram, there is a GR from fuse 11 to the fuel pump relay and to the ECU. it also appears to go to the ignition coil..
I should also say - i'm not an expert...!

The ECU is referenced in the following wiring systems (not just the Engine electrical)as well
Grounding Distribution
Air Conditioning
Anti Lock brakes
Cruise Control
Immobiliser
Oil Pressure & Temp Gauge (RHD only?)
Radiator Fan (with or without A/C)
(unfortunately I only have the 97 edition of the service manual so there maybe some differences)
