i have a 7th generation (2002) civic si with a k20a3 i belive but i cant figure out what kinda obd i have it has 5 places to put things in...1st 2 have harnasses in them and then one with pins bot no harness and then a blank one no pins and one with wire harness going in it....can anyone help???

 

your car is obd2 from the factory, but i can't help you any more than that

 

OBD2b (pretty sure). Why are you asking? and the one is blank bc I'm assuming you have a manual transmission, if you had an automatic the one with pins would have a harness.

 

yeah.. it has (from right to left) one grey harness, one empty spot with no pins, one empty spot with pins, one white harness, one grey harness, and yeah i was looking online for diagrams and none of them (actual pix of the obd) looked like mine so i was confused maybe its just me idk
