Ok I have a d16z6...
I have a 91 crx si with a cut wiring harness and everything and im having problems tracing wires and so fourth since I got the shell already messed up...Im going to call the motor harness an si wiring harness but I really dont know...

1.I know I will need the ECU conversion harness with a p28 to run the motor correct?
2.The si engine harness doesnt have a few sensors that the z6 has, im not sure what it is but on the back of the block there looks like 2 sensors, one looks to be like a knock sensor and the other is right next to it buit im not sure..... the are 3 wires that are close to the sensors but im not sure... 2 of the wires were connected to each other
3.On my si harness It looks like im missing the two sensor wires if im even supposed to have them on it for the TPS sensors?
4.On the harness there is a 3 pin connector down by the starter and im not sure waer it go's?I cant seem to find out were it go's?
5.I have the resistor box for the fuel injectors but what do I have to do to take it out...
6.I cant seem to find the wires I need for the vtec stuff? There was a sensor about were the vtec 2 pin connector was but im not sure if it go's there, there is aso a single black wire next to the vtec one pin connector but the harness doesnt have a connector to it...
7.Were can I get some wiring diagrams for the car...I dont have the money to go out and buy a book...

I searched and cant find any threads refering to the same stuff, I read on the feul injector parts but I really dont want to go thru and read thru it right now, Iv been out side trying to get this wiring down right and Im getting really fustrated...Im also doing a wire tuck so right now im just trying to find out were everyhting go's so I can lable it all and get the tuck done...along with ripping off the front end off and welding on another because the headlight shrouds were cut up by some idiots...

So can I get some answers to some if not all of these questions?
As you can see I have a really big project in front of me and im new to the CRX, I have a CB7 and thats what I really know...
...Thanks alot...
Derek

Edited....I will ge3t some pics up and put them with the number of were I posted them...

2.Back of the block were the 2 sensors are and the three wires...



4.The tree pin wire by the starter...

6.The vtec stuff...


Also other stuff I didnt post earlier...
There is a wire on the back of the intake and I think it go's into the FICV if thats what that is...Is IT?

There is some kind of sensor zip tyed to the fuel wiring and the 2 wires were cut to it but the wires that connect to it come out of the harness by the altenator...

Also what if I put a BBK throttle body on? I have got one from my brother its a 62mm...but im not sure how the car would run with it...Should it be ok with it?


And misc photo's of my project...

back of the block with 2 prongs is for the cooling fan, on the z6 it is probably on the thermostat housing. having those 2 wire together probably makes it so the fan comes on all the time

4.The tree pin wire by the starter...


idk what that is

6.The vtec stuff...



vtec solenoid

that is the iacv will be a 2 prong

that zipped tied thing is the iat sensor, goes on the intake manifold

This is for Supertuner12010...you have a d16z6 correct .me too i just did the same swap for my sedan.I had the si wiring and everything.Well its getting dne within the days well i had the same wiring problem for about a month nobody wanted to come do it for me .. but then again everybody was driving their car though ..so eventually i found somebody and he had a Integra DA Well he gave me the engine harness for his cause he had a extra 1 ...the si harness aint gonna match up like mine didnt.. so with that harness 4rm the DA everything match up exept fot the o2sensor and the vtec he running them ...and everything else is a plug and play situation sry for the whole story but try using a stock harness to the crx and u might have to run about a couple wires...(doesnt matter if it wasnt vtec cause your runnning your own wires..) not really sure how many wires ........so goodluck and hope u finsh your swap post some more picS when its dne

 

oh and if you need any wiring try http://www.rywire.com but yea your gonna need a p28 ecu and a jumper harness u can get that on ebay obd1 to obd0 put that in on ebay the harness will pop up thats what i got mine from any map sensors or any sensors if they dnt fit the throttle body or any where else u could out them somewhere else trust me i got mine like that and dnt let ant one tell u other wise mines almost dne and i gotta a pro doin mine

 

Oh 1 more thing as for the Harness when u order it it will come with all the directions just repin nd play ant more questions just ask i knoe how hard it is to find help and if i dont knoe i'll ask my wiring tech iight good luck

 

If its not to much to ask could you help me out and tell me were you have some of your connections at...For instance the Green/White and Red/White leaning against the vtec solenoid, were does that go?

So if its not too much to ask could you tell me a few ohers I traced down today...Some had connectors and some didn't...

...The List...

....These are on the back side....

(Blue/Yellow
Black Yellow) Go's into a 2 pin connection...

(Yellow/Red) You said its the Pressure sensor

(Yellow/Black
Black) you said it was for the fan switch, which is right next to the pressure sensor right?

(Green/White
Red/Yellow) I think thats the one that is zip tied to the fuel wiring harness

...These are on the Passenger side...

(Green/White
Red/Blue
Yellow/White) These ones didnt have a connection they were just all hanging there

(Green/White
Yellow/White
Yellow/White) This is the 3 pin connector near the starter...

(Green/White
Red/White) These wires were just sitting there along with a thicker grey one, that is insulated and has a white wire underneath...

Another question...when doing this swap, arn't you suppose to convert your dizy to OBD1? And rewire the connections? The motor came with the dizy and the harness connects directly to the dizy? Is it possiple the people I got it from already rewired it? How could I acctualy tell?

Blue/yellow and black/yellow 2-pin connector is for the EACV on the back of the intake manifold

yellow/red is the oil pressure sending unit on the back of the block by the oil filter

yellow/black and black - don't know of a connector that has those wire colors - cooling fan switch is yellow/green and black

green/white and red yellow is the Intake Air Temp sensor on the intake manifold - white diamond shaped where the sensor attaches

green/white, yellow/white and red/blue is for the TPS on the throttle body

green/white, yellow/white and yellow/white - don't know of a connector on the Si harness with these wire colors, however, the HF harness has a three wire connector like that, but the wire colors should be green/white, yellow/white and yellow - sounds like you may have a HF harness on it, which would mean you have a lot more problems than you think - the HF engine harness is not compatible with the Si chassis harness

green/white and red/white is for the ECU temp sensor on the end of the head below the distributor - the white wire with them is probably for the O2 sensor

 

Great info...that clears up a lot of problems...I couldnt thank you enoigh...

I got the ZC from a friend who had it in his hf...why isnt it compatible with the si body harness? Will it not hook up to the connectors by the fuse box? I haven't even tried...Although they look as they would fit...

I haven't even tried...Although they look as they would fit...</TD></TR></TABLE>it will plug in but it won't work - all of the wires (except for one) in the connector on the driver's side are in different locations - the biggest problem however is that the Si harness has the wire for the igniter in the passenger side connector and the HF harness has the igniter wire in the driver's side connector - it will plug in but it won't start and will throw code 15 for the igniter

 

Do I need to get an si harness? I also heard that I think the intagra harness would work?

What do I need to do and what harness would be the best?

 

best thing to do is get 90-91 Si harness

 

yes getta 90 91 si harness lyk me i have a 89 civic sedan and the original harness can work with the d16z6 all i had to do was add 2 more injectors,vtec,o2 sensor,but lyk i said i used a 92 DA harness just a plug and play situation hpoe u finsh ur swap man post some pics up wen dne

 

If your using Z6 injectors with stock ef si harness you need to either solder in z6 injector clips or use a razor blade and cut out alittle bit of the inside of the stock injector clips so they will fit over the z6 injectors. Another helpful hint is you dont need the resistor box which is located driver side by firewall ( silver box) So just take it out then take all the wires and solder them together=P
