I need to run a power wire from my bat inside my 91 HB.

Where is a good spot on the firewall to go through?

Thanks

 

There are grommets on some parts of the car that allow you to find that. You just have to fine them.

 

Depending on the trim level of your car there aer a couple of spots that are Ideal to run heavy guage power wires through from a reloacted battery. In my setup I actaully used EMI shielded, sliver plated expensive ****, and ran it through the gromet that all the ECU wired com in through. All it takes is a small cut on the way though the gromet, becareful not to knick your wiring haness.
Or if your car without a/c, you could use the hole the the a/c lines normally come through. You'll prolly have to drill or cut a hole in the plastic/rubber block-off plate.
