k guys the issue im running into is that im doing a swap in a 95 civic that already has vtec, i know that all I have to do is wire up ur IAB and knock sensor.

Here is the diagram.

so from the looks of it..
when i wire up the IAB, do i manually remove the wire from the A20 slot and insert that wire in the A17 slot? or do i just splice in the A17 wire and solder it on ?

& when i wire the knock sensor, do i manually install a wire into D3? and then run that wire through the fire wall to the knock sensor itself?

right?
am i doing this wrong guys?
am i doing this right?

sorry this is a noob question & is pretty straight forward but im having issues with this ;s

any help would be greatly appreciated!

thx again gentlemen!

 

well if it has ks wire just tap into it, not sure about other question

 

but i thought they were different?

 

anyonee?

 

Depin A20 and insert that wire in A17, plug the evap purge solenoid connector into the IAB box, done.

Yes.

 

thx 94eg8!!!!
only question i have is..

when you say plug the evap purge solenoid are you talking about A14? and i place that wire in A26 ?

 

No. The evap purge plug in the engine bay goes to pin A20 at the ECU, since most people swap in a JDM GS-R with no evap purge solenoid (even if its USDM not having it plugged in wont throw a code or affect how the engine runs, so long as its an OBD1 ECU) its easier to just move the wire over to A17 and plug the unused evap purge solenoid plug into the IAB box, basically it saves you from having to run new wire.

 

ohh alright ill check that out thx...

heres another noob question
when i take out my p28 and try to connect the p72 the connectors dont even match ;s;s

i thought this was a simple plug and play ?
;s

 

You haven't got an OBD1 P72 then, you've got either an OBD2A or OBD2B variant. Get the OBD1 version.
