ok ive been searching on the web for hours now and nothing is coming back that helps. im doing a b18a1 swap into my 90 civic base model hatch TOMORROW!!!. DPFI-MPFI wiring seems to be easy to find info on...BUT, im using OBD1 plugs/wires to bypass the injector resistor box.

i need info about DPFI-MPFI wiring using OBD1 plugs and no resistor box. what i need to know is, what color wires to connect to what other color wires..and what pins on the ecu harness to switch around..as well as any other useful info on this. I NEED ANSWERS ASAP PLEASE!!!!!!

 

same exact way as wiring from DPFI-MPFI. but instead of the colors matching, use the opposite ones. I had to do that w/ a friends, turned out the injectors were staying open. you can use obd0 plugs. and still bypass the resistor box.
