no.

harness and ecu. second o2 sensor will be a dummy.

Exactly what are you trying to do here?

What kind of car?

What kind of engine, and what year engine?

Does the car have to pass emissions?

 

i am puttin my h2b (h22 with b series tranny) in my 97 ek hatch. no the car does no have to pass emissions, and the motor is a 95

 

yes i was wondering also if the 96-98 ek civic automatic ewh is diffrent from the 5 speed harness, i heard it was. since i gotta wire it up for an h2b swap

 

96-98 auto and manual harness are different

 

If you dont modify the harness your brake lights wont work like mine

 

i just did the same swap. if u want to do it the easy way u can run a obd2 p13 ecu or convert like u said. if u use the obd2 ecu then use the obd2 h22a4 injectors because they are saturated. if you use the obd1 p13 than u have to use the obd1 h22 injectors and wire in a resistor box, pain in the a**. if u are using a obd1 p28 or p72 than u still have to use the obd2 h22 injectors. they do not reqiure a resistor box. so its like this,

obd2 p13 or obd1 p28/p72 chipped for h22 then u use obd2 injectors from h22a4
obd1 p13 then u use obd1 h22a injectors and have to change clips and wire in resistor box

now as far as the dizzy goes, im using a obd1 dizzy with internal coil on a complete h22a4 swap, u can use obd2 also but make sure the dizzy has internal coil some came with external.

hope this helps u out. maybe u can answer this simple question for me, what lower radiator hose did u run. some say stock h22 and some say del sol vtec but what engine there is a sohc and a dohc vtec in del sols

 

ok thnx for the help, but i think imma find a 96-98 ex harness since they are already wired all up id just extend some stuff. as for the radiator hose idk yet i dont have the motor in the car yet, we gota convert it over from auto to manual. i think when we had i in the 91 hatch we used the 91 ls radiator hose
