idk i think the problem your facing is your trying to splice obd I to obd 0 im not to sure about the obd 0 to I conversion but i bet you can search for something on it

 

what the hell are you thinking!! I actually picked up a ef hatch with a b18 installed crooked and a da harness spliced into the ef harness in the attempt to convert to mpfi. Only pysas do that kind of stuff. And of course it didn't run. I got it for free cause they didnt' know what the hell they were doing. I had to get some real mounts and then another harness.

Don't even try to do that.

 

no....use your ef harness and add wires to make it run the motor you want. not real hard! jeez...and dont be a broke *** trying to wire the entire car and hack it up for no reason. i see sooo many hatches that are cut to shizz trying to do this. gayyyyy

 

i only ask cuz i cant find a si harness

 

i converted mine its a whole 4 added wires and extending a few plugs, solder everything

 

why do you need an si harness...isnt your car already an si? whats wrong with using your current engine harness?

 

my harness is si its bad its been getto rigd i had bought it like that, on my harness a few sensor wires are missing the actual connector, to the o2 sensor, block sensor and the center on the head. I havnt bought an SI harness cuz i cant find it...
I have a 91 integra wharness it was just sitting their. i wanted to spine the wires for the connecters, same fit but I don't know if it'll work.

 

You just answered your own question, the plugs fit so yes you can use them. Just take the plugs along with the lenght of wire you need to replace what is missing solder them together and use shrink tube to seal them to the elements.
PS make sure you use electronic solder and fluxing paste. Not acid core solder it will eventually corrode the connection and you will get dead shorts or broken connections.

 

u have to splice a da harness in if u cant get a si harness it will plug in to all but 1 if i can remember right and on the civics its a rectangle plug and on da;s its round them need to be spliced and the fan switch sensor with the 2 tittys coming off it needs to be wired in and one other wire i cant think of right now
