Okay so as to try and figure out my problem from the other posts I had. I am trying to figure out if anybody has a diagram that I can use to wire an obd2 b18b1 into an ej1 '94 civic ex coupe. The car runs, but doesn't rev to 7k like it is supposed to and not getting the proper mpg, even with a virgin p75 and no check engine lights.

what are u trying to wire if u used you 94 civic wire harness switch to an obd1 td55u dizzy and use the virgin p75 ecu u should have no problems u wiil not have a crank sensor plug on your harness but u dont need one as long as the ecu is obd1 u will not have any codes also is this car automatic

well it was automatic, but now it is manual. It still has the neutral switch wired up to the car. I was told that is only for sending the signal to the starter.
