I have done a lot of research on this site, h22.org, and on the web. I have not found a good description of the wiring involved in this swap. I do have a B16a swap into a 4th gen civic under my belt, but there was a lot of info floating around about that one. I am uncertain of the ecu, but i am told it is a obd1 -the engine is from a prelude (92-97) and it is going into a 91 accord, which to my knoledge is an obd0. As far as I know, all i have to do is hook up the VTEC solenoid, Knock sensor, VTEC oil pressure switch, and oil temp pressure. But is there anything else?? If anyone can help, i would appreciate it. Thanks in advance.
