h22.ej8

Hi. I did a obd1 h22a swap into my 99 civic. the people who did it used the civic harness. they left the civics iacv even though i took them the prelude one. the thing is that they didnt connect any hoses and capped off the ones in the IM. Not it throws the check engine light for the iacv. should it work if i connect the civic one??? any help would be great. thanks in advance!!!
