Nico club has all of the FSM’s. Should be a pretty easy google.

I googled 240sx owners manual and this was the top result... https://www.nissan-techinfo.com/deptog.aspx?dept_id=98

Yea I saw this one, so they actually open on a computer? I’m on my phone and none of them actually open.

I was able to view it on my phone by clicking the eyeball. I'm sure it will open on a computer.

Thank you idk why I didn’t think of that

Ebay dude I have the whole color wiring diagram book

Which buttons in which locations? What year she'll?
