One of my teammates is thinking of switching his car from OBD0 hatchback to a OBD1 and wants to know what all he'll need? Please need help ASAP!!!
 
A conversion harness from hasport or some members on here or honda-tech. You will need a 4 wire o2 sensor, an obd1 ecu, an obd1 wiring harness to grab sensors and connectors from, and a spool of wire and some tape.
 
Mine costed me 100 for the conversion harness, 75 for the ecu, the harness came with the engine, the o2 sensor was free but you could probably find one for 50 bucks. I did this a long time ago so I don't remember how to do it or the exact wires to change. When you order your harness you should get some directions with it.
 
Well I'll let him know roughly $300-$400 dollars, Thanks!! If anyone knows of anyhting else he might need please just reply!!
