Hi All.
Like it says, does anyone have the pinout for the interior diagnostic connector in a 1989 crown? I specifically need to know the function of the blue with a yellow stripe wire. It seems to be the +12Volt battery wire but the voltages I see on it indicate its not, or it is modified in some way. The same wire goes to many other devices (eg ECT, speedo, etc and comes from the PCB under the interior fuse box.

Thanks all.
