I need to know what color the wire is that I need to tap into going into the ECU for a A/F gauge.

Or can some one post a link to a how to on it. https://www.nopistons.com/forums/pub...#>/biggrin.png

Just run a wire to the oxygen sensor and tap it on the o2 wire side. If you tap into the harness side you have to be carefull not to tap into the shielded part of the wire or it will fry the unit.
