can anyone give me a list of all the wiring i need to do? I have searched and haven't came up with conclusive info. Here is what im doing: OBD1 jdm b18c (sir-g) into my 1993 civic cx hatchback.

 

about 98.5% is plug & play...

 

yea i know i have most of it done, Is this correct what i need to do:
ad wires for vtec
wires for knock sensor
wires for iabs.

I know that much, but dont know how to do it

 

you could purchase the addon harness from Rywire.com to make it easier.

 

i have the cx to gsr subharness from rywire, but i have no instruction on how to do it, ive never done this before/

as far as vtec wires, i run those directly to the ecu, installing pins is the other way but you'll need a terminal repair kit or something like that. if you still have the jdm harness you can use that vtec plug then run the wires. i use the soft connectors with rosin core in the shrink wrap, so when the rosin settles it seals up.

same with the knock sensor but that is one wire.

if your using a single stage intake like blox or s2 manifold you don't need to wire iab you won't even get a check engine light.

 

do i have to run the wire to the ecu for vtec oil pressure? the jdm engine doesnt have the oil pressure sensor

 

yeah don't worry about oil pressure switch, as long as you have a jdm p72 not a usdm p72 you'll be fine (same thing with a base map)

 

yes i have the jdm p72, i know what i need to do now, Thanks a lot for the help.

 

no prob man
