It is not anything hard to do, i did the same thing for my b16 swap. Just cut the obd1 plugs off of the distributor and cut the obd2 plug off your civic distributor. I'm sure you have already done this. Leave plenty of wire so you can have room to work. All you have to do is match up the wires and solder them together. I say solder, not twist and tape. There is the same number of wires and the colors match up.
