Hey All,
Looking for 1991 Mazda B2200 ECU Pinout chart.
I have the diagram that shows where the wires go from the ECU to the distributor
but what i don't know is what does the pin on the ECU do?
Also...i know there are a few versions of wiring diagrams out there....the particular one I'm looking for is
the one with the 4-wire distributor.
Like below
[(Pink)(Black)(Yellow/Blue)(Black/Yellow)]
I know the black is ground.
and
the black and yellow go to the injectors
Q: What does Pink and Yellow/Blue do?
