the main problem im having is the si wire harness only has 2 plugs (B,C)for the ecu. because the first(A) ecu plug is a part of the car on a si. so what would be the easiest way about doing this. i want to get this bitch b.a.r. legal.

1. get a 99 ex wire harness and adapt it to the b-series
2. wire the A plug into the car
3. get all the wiring from the si
4. shoot myslef in the head
5. shoot the guy i bought the motor from
6. fu*k it

 

I am having the same problem, and that is the 99-00 SI harness has two parts the interior and extrior harness. So if when you got the harness for the engine you did not get the one for the interior it is almost impossible to make the engine work with all your stuff. The simplest fix, what I did, was get a harness that matches the model that you need. So if you have a 97 then you need to get a 97 harness and adapt it to work with VTEC.

 

so how do i get it smogged? and what ecu did you use? i went looking at harnesses and they are all the same for ex from 96-00 its gay honda really fu*ked up this one...

 

come-on its not like this is an un common swap...

 

Yeah, if you get an EX harness it will work right. Just get rid of the SI harness, or sell it on EBAY, then you will be able to use the B16 ECU. That is what I am using for my swap, until I can save up and get AEM EMS.

 

what year ex harness, i went to H-auto and looked at all of thier harnesses for 96-00 and they were all the same OBD2a i couldnt find a OBD2b unless thier **** was marked wrong...

 

yes you need a ex harness.. 96-98 obd2a, 99-00 obd2b

hope that helps

 

use ur old 96-98 civic harness, get obd2a-obd1 conersion harness and run p28. this will leave u more option for chipping, f/i

i got the car running today. i took the harness off of my ITR motor and ran a p73. its good and all untill smog time...

 

good ****

 

If you have a 96-98 ek, then you need an 96-98 EX harness and 96-98 ECU. If you have a 99-00 Ek then you need a 99-00 Si/ EX harness and 99-00 ECU. This is if you want all the Vtec stuff there.

You can reuse yoru CX/ DX harness and add what you need as well.


All the info you need on the swap is just a click away, check my sig.

WTF? The teg harness is two piece and the Ek Civic harnes is one piece??

 

i took my o.g. ek 97 harness and addapted it to work with my itr motor 96, that was previously in the car...and i just got a eg hatch that i wanted to put my itr motor in. so i bought a 99 b16 for my ek. so now im up **** creek with out a harness...get it? i have a si ecu which is obd2b and plug A is apart of the car on the 99-00 si and the harness i have is obd2b missing plug A. but the harnes im using now is off of my itr which is obd2a....with a p73
