how do i pull codes on a 1989 civic Si with a D16Z6 swap? i cant find the plug im supposed to use O_o

 

should be under the passenger dash eather a blue or gray 2 pin plug.

 

that's what i've been told, but i cant find one anywhere, is there any other way?

 

did u use a jumber harness they should have 2 wires u hold together and get the codes!!!! goodluck

 

i just bought the car like two weeks ago.. has what looks like an adapter harness or somethin for the ecu.. is that the one your refering to?

 

bump

 

im gonna take a pic of everything in the passenger side tomorrow so maybe you guys can help me out a bit more seeing what i see

 

<U>1989</U> i'm sorry i missread. the plug your looking for is a yellow caped plug on the fender wall drivers side. its between the shock and the window washer fluid tank under the hood.

 

awsome! thank you im gonna go check right now

 

i dont have that plug either, what the hell!!

are you sure that's where its supposed to be? or do you know the wire colors? maybe the guy who owned it before me just cut the connector off

 

does it make a diffrence if it's a hatch? just wondering... there isnt anything i can do at the ecu is there? it's a P28 chipped with S200 hondata... i dont have datalogging so i cant read them that way and i cant afford the upgrade right now

 

call the guy back and ask if he ever hooked up some kinda yoggle swith for the codes.make sure u have a 4-wire 02 sensor and a z6 distributer.on the jumper harnes at the ecu, there should be a piggyback one that goes through ur firewall for the vtec wires,o2 wires,and some kinda toggle swith wires.

 

if you havnt figured it out the harness should have a sub harness going into the firewall there should be a yellow andblack wire if the jumper is from locashracing hold them together

 

i dont see any wires going through the firewall but i'll check in a few minutes...

 

I got a 89 civic LX 4 dr witha d15b8 motor, engine light keeps coming on after about 10 min of driving and dude said it was the speedo cable but that didnt work, i need to figure out how to get the codes also. Let me know if u got anything u can help me on. Thanks
