Icon3 1991 Civic hatch ECU wiring schematic

I'v been searching for the past hour and CANNOT find any 91 Civic or CRX ECU wiring schematics. I'v downloaded the shop manual for the 88-90 Civics but the ECU wiring schematic does not match up on my 91 Civic hatch.

Does anyone know where I can find the ECU wiring schematic for free?

My ECU wiring harness has been cut and I need to splice it back together. Also, my engine is MPFI, not DPFI.

anyhelp greatly appriciated!

-Dan
