I've seen all the write ups and understand it all... But... I have a problem.
My brothers car is a civic ef standard model when he got the car they had convertered the interior harness to an si harness ... And he ran the car fine like that with a dpfi motor engine wiring.
So we just swap a d15b vtec motor but had no engine harness so I decided to use the dpfi engine harness and convert it... From my understanding si harness are different than dx but now I have no spark, no fuel, it's not cranking and when I try to start the car I have the brake light on .. So all plugs that go to ecu (A ,B and C) ( A1,A3,A5,A7,A15 are wired direct to the injectors and resitor box ) plug B and C I put them back to normal locations... Any ideas on what my problem might be? I'm thinking it could be the dpfi engine harness... But if I can make it work why not. And where would I wire the 2 cable for the distribution that go to c1 and c2 when doing the conversion?

 

what you need to do is get a regular dpfi harness and do it c1 goes to blu/yel on the dizzy c2 goe s to blu/grn on the dizzy and if theyre backwards just switch em ill have to go look on mine...you need to move the existing wires at those the places to b10 and b12 then run wires from pins c1 and c2 to the dizzy.

 

Dpfi interior harness? that might be the easiest way I think

 

^hahahahaha

 

you have to convert your dpfi harness to a mpfi harness very simple.

check this link out maybe this can help you. Double check the wiring over and over.
