I just swapped a B18C into my civic. After about a week of getting new parts that would fit we finally dropped the motor in over the weekend. The only questions i have now are wiring related. If anyone could help that would be great. I originally had the stock D16 in my 93si. i am guessing it is OBD-1. I was wondering if it is possible to use the wiring harnes on my b18c and just add the vtec lines...etc. the engine came out of a 89 crx and was wired for use with that car. would this be a problem? any help would be appreciated.
