Does anyone know the pinout changes between the early (yellow)
and the late (blue/green) MAC02 ECUs?

Subject: [urq] Looking for a MAC-02 for 1983 URQ
Anyone have a MAC-02 (yellow label - early) for my
I am reasonably confident that my FI issues (duty cycle stuck @50%) are
inside the ECU. According to the factory manual, the duty cycle should
be around 70+/- 6% with the idle switch disconnected and the FT switch
triggered. Unfortunately, I get 75 with both idle and FT switches
tripped. Having checked every wire going into the ECU, the diagnostic
flowchart leads to "Replace F/TCU."
So, what I am looking for is a MAC-02 to buy or to borrow to isolate the
problem. In the borrowing case, I would pay postage both ways. Can
anyone help me out?
