My question is just what the title says. I tried searchin for the answer but I couldnt find anything... Im swappin a B20b into my 95 del sol si... Im gonna be converting the motor to ob1 usin a P75 ecu and an obd1 distributor. Since my stock wiring harness for my D16y8 is obd1 can I use it for the swap?????

 

If you have a Y8 engine, sounds like it's been swapped out. The 95 del sol should still have the Z6 motor, which was swapped out for the Y8 in the later years (96 up Civics, for example).

If you have a P28 computer now, then the harness that connects to it (via the engine harness, of course) will also be compatible with the B20 engine and P75/PR4 computers (obd 1 style).
