I've figured out that the 92 vx has the five wires 02 sensor. So, in my case all I need is to plug in the fed ECU and go, correct? Or do I need a different style o2 sensor connector even though I have the 5 wire?

Thanks monroe for the links.

You're good with the setup you have.

As smccall said, yes.

And I would keep the old ECU around. If you or a future owner wants to register the car in CA, then theoretically you could have a smog problem. Temporarily swapping in the old ECU would be an easy way to get around that.
