This is so I can run heat temp line Oil pressure line and water temp. Too a set of sun pro gage's. So where would be the best place to put the hole so it dose not inner fear with any thing else like windshield wiper or other stuff. Any ideas will be appreciated want to do this while cutting holes for Ac hose's. Want to seal the holes with paint.

You could drill the hole for the factory tach wire. It would be a factory correct hole location. I think the factory hole might closer to 3/4" or so but you could probably drill it for a 1/2" car-plug if you wanted?

I believe I ran mine through the speedometer cable hole cause it already has a grommet for that

Well think I will opt out on the gun. I have a set of hole knock out set used in putting holes in electrical panel boxes. No powder burns around the hole this way. :lol:

I just drilled a hole to the left of the glove box as high as I could get it from the inside.
