I am in the process of installing the Field Hyper SFC on my car. I'm running into a few problems in finding some of the wires to tap into on my ECU. Now the manual's diagram of the ECU harness is different than mine (maybe they changed it in 99) but I have found the speed sensor, power and rpm lead, but I'm having problems finding the O2 and MAF lead. Looking at the haynes manual it seems that they are both white, along with 50 million other white leads into the ECU.

Can anyone tell me where they are on the ECU or should I just hook it up in the engine bay?

Also which O2 sensor do I use or does it matter?

And on the back of the controller itself I only flip the #1 switch on right?

Thanks,
Matt

Do you know how to trace circuts using a multimeter? Trace the wires back from the source to the ECU. Sorry I dont have time to crawl under my dash and look for the exact locations.

Thanks, I'll try that. Does it matter which O2 sensor to wire into? I tapped into the right bank and it says that I am lean all of the time, which I know isn't right.

The O2 is not really needed, but if your car has a rear one before the cat use that one.
