I find this a little hard to believe, but after searching, I can't seem to find any install tips for an a/f ratio gauge in a 06 s2000. I need to find the ecu signal wire, but there's 4 connectors plugging into the ecu, so I don't think it's #16 on the C connector. Can anyone help me out?

 

oops, I posted in the wrong section. Ops, can you move please?
