Where to tap into 12 volts?
Where is a good spot in the engine compartment to draw power - 12 volts switched through the ignition? I am putting on an Autothority MAF (among other things), but I don't really want to cut into the ICV harness to tap into the power.
Any recommendations? Thanks, Mike |

On the left side of the engine bay there is a fuse panel under the black plastic cover. There are a few switched power fuses. Depending on your car's options they may be unused.

Yep. I agree with JB. That fuse panel is switched. I have a mini hourmeter in the engine bay that is powered from that panel.

NOT ALL are switched. Verify with a meter or test lamp. Use an appropriate fuse.

Yes, I should clarify. Some are switched, some are hot/12V constant. A recent thread on fuel filter replacement reminded me of that.
