Which wire to tap for Air/Fuel gauge?
The instructions say not to tap directly off of the O2 sensor wire, but rather off of the wire going to the ECU. On a PR3 ECU, which one is this? Thanks

If the wire off the O2 sensor isn't shielded I think you can just tap that, thats what I did, and it works fine. Otherwise, I dont know the exact wire

I didn't think it was shielded until I got no reading, just one LED lit on the Rich side.
The PR3 ECU is from the JDM B16 engine. PR4 is the 91 integra ECU, etc.

What is a good wire to tap the red wire into? I know it says ignition start wire, but is there an equivalant wire that is easier to get to?

Just a note... for the A/F gauge make sure to get ground from chassis ground or the actual ground wire at the O2 sensor... else it can be somewhat (more?) inaccurate.
