Default b20a5 into 81 civic! need ecu wiring help.

i just purchased a 90 prelude si for the motor, ecu, and all of the fuel and brake systems. i am trying to swap the b20 into my 81 honda civic 4 door, but cant seem to find any info on swapping an ecu into a car with no computer. i am not using any power windows, locks, a/c, abs, p/s or any other comforts. i just want the motor to run right an then ill upgrade it from there. if anyone has any info on ecu wiring that would be great.

I think you're gonna need a standalone ECU to convert the car to EFI....
