Default wiring gauges

I need to wire in my boost gauge and wide band however I do not have a clue where i should wire in to the car. Does anyone have images on where they wired in these gauges.

If refering to where to get gauge power, assuming low power digital gauges, I wouid tap into a Power On fused source.

For example, my Cobra radar detector has low current draw so I just tapped into the RVM light power (on when Power On).

Do I just grab power from the headlight switch or do I run my own power line from the fuse panel

When I wired in my wide band A/F gauge I removed the panel over the shifter in the center console and found a switched wire to run both the gauge and the heater for the 02 I can't remember which wire it was but with a simple tester you can tell which one it is, on my 93 it was very easy to find. I mounted the gauge in the dash just below the radio. Good luck.

Did you drill a hole in the the tunnel to run the wires or did you run it through an existing hole to wire in the O2 sensor

Your FSM for whatever year Vette you have will show wire details.

What does a WB O2 require save for power, gnd & signal?

I figured it out. I think I may have been too tired and stressed out. .. I ran the switched on power from the fuse block and grabbed a ground from the cigarette lighter.
