Ecu question

[Miatch]

I have a 93 honda civic cx with no rpm gauge so I am going to put in a proform tach, and before i decided to do anything i would take a look at the ecu to figure out where to put in the green wire. Now my car never came with the users manual so i was just curious if anyone had a picture or even could just tell me where to put the green wire because i dont know where the tach terminal is. any help would be appreciated!!

you could also feed it through the firewall and connect it there(if the green wire is long enough). Less work but not as clean looking.
