| Installing Air Fuel Mixture Gauge |

Because tapping off the sensors involves real heavy duty
wrapped-insulated wiring (unless you grab further
upstream somewhere), you can grab the H02S signals from anywhere (from either R or L or both sensors) thru the O2 sensors's 'signal' wires going to the PCM.
- Just tap both Left and Right HO2S signal wires at the bundle-stalk connector in engine bay over by passenger side hood gas-strut shock, right behind shock tower and against firewall.It's a vertically-positioned kinda square-topped connector there. You'll see it.
- Put some 18ga. taps there, then route in thru firewall (there's a huge -unused- rubber grommet at firewall just below -at that area also which comes thru up inside below the glovebox area but way up above carpet edge top area)
- Inside, you'll need a 12v+ switched power tap (H in Start/Run), a ground, a light circuit tap w/grnd (and to be safe an in-line fuse along the 12v+ power tap).
- Then you can grab a DPDT toggle to allow both L or R sensor or OFF monitoring
- Once you've placed your toggle, it's on -with the wires to the A-Pillar where you'll route wiring and make connections to the A/F gauge and install your 1, 2, or even 3-gauge pod Pillar setup.
- The A/F gauge (at least AutoMeter's Phantom line) has nice real tiny, thin gauge wiring (looks like 22 ga. or smaller wire size) that's all color coded that you can route down thru piller pod mount and into behind dash area, so you can meet your other wiring to solder connections and save 'sqeezing' any more wires than absolutely necessary.
