ok i have a obd2 b18b going into my 97 civ HB. wiring wise i dont have to change any harnesses. just plug and play? im staying non-vtec to go boost later. i just want to confirm this.

Probably the best write up on wiring in a ek for any b series swap... enjoy.. compliments of KATMAN

 

You have to use the CX or DX harness that came in your car.

Take that harness and put it on the B motor.

Switch the ecu pins and sensor plugs where needed.

That's it.

check the "EK Swap Guide" link in my sig.

actually grab a EX wiring harness.. and throw it in there..i am doing the exact same swap as u.... and katman told me to grab a EX wiring harness... and it plugs right up.. and just leave the vtec wire hanging.. and the good thing about that is... if u ever do decide to go vtec or grab a vtec head... u already have the vtec wiring right there... and that's it.. plug and play with the EX harness... other wise u have to convert the IACV from 3-wire -to- 2-wire it's easy from what i hear... but y not make it easier.. ya know!?


U can pick up a wiring harness for a EX for like $100+ from like a junkyard or something...

 

:sigh:

Actually the CX and DX harness will do fine if you are on a tiiite budget (pun intended).

EX harness is butta. ( I used the EX as well cuz I was lazy)

 

hey.. thats exactly y im using the EX harness.. hahaha im too fat and lazy to re-wire.. lol

 

well what happens if you have a autoEk and want to change it over the ManualEk, what then. Could you just use all the wiriing from the B18B.

 

i wouls assume u could, but u still have to change some thing's around of coarse...

 

So basically just use the EX wiring harness of my year model. Correct me if im wrong

 

yup, that is what i am doing... and a guy that i know pretty well, did the same thing to his EK hatch, when he swapped his b18b into it.....

in fact, i think he had a at. and converted it to mt.
