Ok so my dad calls hmotorsonline.com and tries to order a b16A SiRII complete change over which comes with the obd1 engine harness. The guy my dad was speaking with told him that because the civic we're swapping the engine into is obd2 you will need to buy the obd2 to obd1 jumper harness. Why is this needed if it comes with an obd1 engine harness?
