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!!!!!!

 

c'mon..16 views so far and no help yet...there is a sense of urgency..please help!!!

 

i dont think your geting a reply because we dont understand what your saying.... your doing a dpfi - mpfi swap and obd0 to obd1?

90 base model hatch...swapping in a OBD0 b18a1...
OBD0 pr4 ecu
OBD0 dizzy
OBD0/1 (both) mpfi wiring harness
OBD1 (92 integra) injectors.....

is this possible/worth the time. Im trying to avoid having to pay out the *** at a junkyard for a set of OBD0 integra injectors...but if i have no other choice then i will. Im also trying to bypass the injector resistor box (by using OBD1 plugs..)....i need guidance on if OBD1 injectors on an OBD0 setup is possible..and how..thanks.

 

why would you wanna take out the resistor box. theres no point in sending that much current to the injectors you'll just burn them out sooner. keep the resistor box and run the wires off of the injectors to the resistor box. positive to resistor box and negative to computer

 

im just gonna go to the junkyard and try to rip them off for the injectors...the obd1 **** looks like too much bullshit.
