A/F gauge wiring

Are you using a wideband?? You shouldn't have to tap into the ECU at all. You need to run a new sensor to you downpipe/test pipe. If you are using a narrow band like the factory ecu already uses, you are wasting your time. It won't be accurate enough to use. It will just look cool.

There are three ports under the dash that you can take 12v from. Constant power, ignition, and lights. Use the ignition port. (I forget exactly which one is what) Just crimp a male connector onto the wire and slide it onto the port. I'm sure someone here has a pic of it that they can show you.

That's the middle one. They are kinda countersunk in the fuseblock, under dash, on the side. They are flat male, you need flat female connectors on your wire, buy them at autoparts, and please install an inline 5A fuse!
And the constant on is the one closer to the front of the car. Check with a voltmeter.
