I have 93 civic with a fully built h22 enginefor turbo. My question is, I have a friend that has a AEM computer for sale but is for a obd2 harness .
He told that all I need to get is converssion harness from obd1 to obd2 and it should work fine and that i don't need anything else.

 

So what is your question?

 

my question is, that all i need to do is get the converssion from obd1 to obd2 so i can use that AEM ecu on my car.

 

yes. all you need is the proper conversion harness, and a map sensor.

 

who make an obd1 to obd2 harness? I have only seen the reverse.

 

boomslang makes them

Yep, I've used their obd2 to obd1 conversions before and they work perfect at a great price!
