how can i tell these things?... 1) weather or not my ecu is obd1 or obd2? 2) weather or not my engine harness is obd1 or obd2? 3) weather or not my engine (b16a) is obd1 or obd2? (i dont know what car it came out of..... last thing...someone told me i need to make some hybrid harness for my engine because it has an obd2 ecu (not sure if they know their stuff) and the engine harness is from obd1....my car has a wire cut so that the fan is always on or else it wont turn on...know anything about this?
