my friend gots a 1990 civic dx hatch with a jdm b16 swap,the harness is cut up,what harness can we use to replace it and have the car running good,or what harness can plug and play or if it needs mods

 

it needs the harness that is for that motor and ecu as well, unless y know sum1 that can make u a harness and wire direct. but im sure only b16 harness

 

ive been hearing that i need to use the stock harness of the car and convert a couple stuff

 

Don't listen to this ^^^ NOOB ^^^ ... just use the harness from YOUR CAR and add what is necessary to complete the DPFI to MPFI. ALL OF THESE QUESTIONS CAN BE ANSWERED IN THE FAQ... you NEED to learn how to SEARCH!!!

 

depending on how knowledgeable you are with wiring. you can get another DX harness, convert to mpfi and add wires for vtec and knock sensor. or you can get an Si Engine and Dash Harness and add the missing vtec and knock sensor.

Or you can contact Rywire and ask them for a DX to Vtec wire conversion harness or DX to OBD1 vtec harness and call it a day

 

off the top of your head how much would one of these harnesses cost?

but since i know most people wont bother to look on the page. here is capture of Ryan's prices. Ryan if you want me to remove it lmk.

 

or you can go to the local junkyard find the si counterpart to your car. spend about an hour or so and remove the entire harness from the car and only pay about 30.00

thats what it cost me and i took the ENTIRE car harness from a 91 crx si. i even have a sunroof switch with oem harness for it, but no sunroof in my dx

 

Bwahahahahaahahahhahahahahahahah!!! CRX S-IR you are waaayyyy too nice to these helpless people. You even took the time to post a screen shot of rywire.com... Now THAT is classic.

 

cuz i know they arent gonna click on the link. i think most of the newbies on here are used to having things done for them.

 

Well why would you feed into them then? They have to get off the teet sometime or another... Oh well... YAY for free post counts!!!

 

Naw don't get it twisted,I know what needs to be done I just needed to confirm b4 I go buying things,its not my first swap or last but it is my first time messing with obdo I just wanted to separate the facts from fiction,read my second post indicates I knew I needed to use the dx harness

 

Also the ecu is an ef si ecu can I stay with it or I would have to change

 

See... you did not do your homework Little Johnny...USDM 88-91 CRX's and Civic's are OBD-0... YES THAT MEANS ALL OF THEM... so what are you trying to do again? Wait what's that? Go OBD-1 you say? Well then, what do you think the answer is?

 

HAHAHA if u listen to this guy then u will end up being a piece of **** just like him, HAHAHA neversatisfied is a cocky **** talker! but hey that is what forums are for right, people giving what they MIGHT KNOW, and people who know and people that talk **** with **** in the mouth.

 

Ef Si?? You mean an ed Si ecu or pm6. You are supposed to run an sir ecu such as a pw0 or pr3

 

"See... you did not do your homework Little Johnny...USDM 88-91 CRX's and Civic's are OBD-0... YES THAT MEANS ALL OF THEM... so what are you trying to do again? Wait what's that? Go OBD-1 you say? Well then, what do you think the answer is?"

Lol again you stick your foot in your mouth,1st I never asked what it was,I know its obdo like I said apperantly you did understand its a crx ecu and what wait what is a crx obdo that's right,I asked if I should keep it or not since I have never heard of obdo being chipped or if it would be better to run a jumper harness and use a p28 buddy,

Don't get me wrong I thank you for the help even tho you don't answer non of the question but read before you post because then you'll be spending time taking your foot out your mouth

 

Or if you want to do the obd1 you will need more items:
obd1 b16 distributor
4 wire o2 sensor
obd1 p30, obd1 pr3, chipped p28 or the hard to find p61
obd0 - obd1 adapter harness

 

Thank you crx_si you actually answered my question,not like other people,im new to obdo not to honda,this isn't my first build,crx_si just to let you know I got the dx harness and tomorrow I start the dpfi to mpfi conversion

 

hey dude post sum pics when u do the DP to Mp, i plan on doing it as soon as i get ahold of all the parts.

 

Yeah I know about that,but that won't be for another month,for now ima use the pw0 ecu and stay obdo for now,my other civic needs to go under the knife so I just want to get this one going

 

Thank you for paying attention to me. Also, I would rather be that then a dumbass like you.

 

1.) Thank you for paying attention to me.

2.) OBD-0 can easily be chipped and tuned. (There are much more options and capabilities with OBD-1 though.)

3.) I would never go back on something I said. I know it all, just ask me.

4.) There I answered a question of yours.

 

No prob ima double check the ecu and post the info,and I didn't know you could chip obd0 thank you for the info

 

hey if i can jack this thread i also have some wiring dramas,

the story with my car is its a ef7 and it had a b18c converted into it, the b18c is missing and id like to put a zc back in. now the prob is my rear harness has been spliced to a dc2 harness has anyone got the pinouts or pics of the rear harness plugs i can see please, i cant seem to find any. the other thing im looking at is the drivers window has been cut to so id like to c where it connects back into the stock wiring harness. thanks guys
