I got an autometer volt gauge and was wondering if anyone knew where the best place was to wire the gauge to?

 

I just tapped into a switched power wire in the driver's side kick panel. It is one for the electric window. I like this source because you can see what your voltage is while the truck is running and while it is turned off....but it doesn't stay hot after you open the door.

 

Thanks!

 

I tapped mine directly into the fuse box. I tapped mine into the 30 amp fuse. I believe it was for headlights.
