Never done this swap, but Motor bolts right in, I'm sure that you alrady know that.
You should only have to run wires for the VTEC and VTEC oil press, to make sure VTEC will works. Is the ECU a JDM or USDM?
As far as the rest of the wiring I dont know, you should really model you harness after an automatic EX civic (D16Y8). when i comes to 02 sesnsor

thank you sir...yea ive bin told the engine will bolt right up and the ECU i have is a jdm one i believe..I bought the motor and auto ECU from jdm engine depot. They told me everythn should go into place except they didnt tell me i needed a engine harness for the vtec to work..the one thats on the motor has bin cut..ppl bin telln me i needed a 96-98 ex harness and others said the harness for the d16z6 would also work great...I got and research alot of good info but i would like more opinions from others who helpd or did these swaps....I sure appresiate ur info Domi31 thx man il take it into consideration!!

Sorry cant be any more help, but dont use the d16z6 (1992-1995 civics) harness becuase it is a two piece harness, your harness is a one piece, So if you plan on switching a harness you should look for 96-98 auto EX Civics.
The reason I asked about the ECU being JDM or USDM, is that JDM motors dont have a CKF sensor and if using a OBD-II USDM ECU it would throw a Check Engine Light.
You have to add wires to get the VTEC to work, if you plan on using this harness.
To me all you have to do is Run wires for VTEC(A8) and VTEC Oil Press (C15) from the ECU to the proper sensors on the motor.

I would go to a junkyard and depin some wires from a ECU harness and the just run your own wires to the proper points on your ECU to the sensors on the motor, here is a link showing the depining process.
