D4 Code 13 and 14 are different in my shop manual. Both codes are pointing towards a bad ECU, or possibly a bad TCU.
My advice is to go to a u-pull-it junkyard and pickup an ECU and a TCU from a 94/95, LX/DX, automatic transmission, 4-cylinder. These are pretty inexpensive.
Look up the OEM part number to ensure you get the correct ECU/TCU. Sites like hondapartsnow.com are pretty good. You can also clear your vehicle, enter the OEM part number, then see what vehicles use the same part number.
You may want to check your ECU fuse in the cabin fuse box and also the 7.5 amp backup/radio fuse.

Oh, and can't get that site to send me the registration email so I can download the manual. I've tried several times.

What are the honda part numbers on the ECU and TCU? They should be on a sticker and be something like 37820-P0A-A51

TCU/ 28100-POJ-901
I have already replaced both with new(used) ones, exact matching part #s. Never got to run the car, but still giving me the same d4 codes.
