20B stock ECU wiring/pin diagram
 

If anyone has a digital copy or selling a 20B ECU pin diagram, doesn't matter if in Japanese, please let me me know, my friend is swapping a 20B into an '89 FC, he wants to use a stock ECU since the initial swap cost is pretty damn high. We found 2 out of 5 20B ECU plugs and some what translated them using the 13b REW diagram. Thank you.

Wait, are you trying to use a 2 rotor stock ECU to control a 20B???

You swapping over the stock coils from the Cosmo too.
Else, this swap isn't going to happen...

Safe to assume he is swapping in the 20b ECU considering he is looking for the 20b ECU pin out.

Of coarse not, I meant stock 20B ECU, might have been unclear and yes, he is going with stock coils
