ok i just ordered my complete swap with everything i need for my 99 civic ex. i got everything for $4000. my question is i am going to do the swap myself and since this is going to be my first swap i was wondering how different are the two wiring harneses on my vtec ex and the B18C1 motor? i know if my car was not vtec i would have to rewire the whole vtec thing in it. but since it has vtec what would i need to do to make it run perfect or would it be plug and play kind of deal? please help!!
