I'm pulling the b16a from my91 DX hatch and i'm confused as to what to do with the wiring to the ecu. Car was dpfi to begin with and I will be putting in a d15 mpfi engine. Do I put the harness back to stock, leave it as is, or what? The ecu I will be using is from am 89 CRX Si ( which will be getting the b16 after overhaul). Searching didn't answer my question.

 

Put wiring back to stock.
Don't forget to move the rear mount back over to the original location.

 

Thanks for the reminder on the rear mount! One ?, I had to wire for multiport fuel injection, do those wires stay where they are? Iwould think they have to for the injectors to work.
