ok so my friend has a 94 hatch with a b16a2 in it... currently hes runnning obd1 with a chipped p28... but hes wants to get ref'd and were wondering how to convert the car to obd2... i know we'll need the engine harness and the ecu plugs, but what else? all the dash wiring also? any suggestions as to how to do it?

 

thats gonna be hard. you need to hook up all the obd-2 sensors and have a diagnostic port for a obd-2 scanner
