I can set your car up to run properly without a narrow band O2. My car fuels great just running open-loop while cruising.

Keep the plug there with power and ground, though. I'll loan you my LC-1 with XD-16 to get the car tuned. I'm done with it on my car. It's setup to plug in to the stock O2 connector. Run power and serial to the gauge and that's it!

I've got a bunch of those odd alternator bolt-eye-with-threaded-stud dealies if you need something to mount that alternator. What about it doesn't work?
