Power cable, Driver's side firewall
 

I'm running the alternator cable through the Driver's side firewall for my battery relocate. I was wondering where a good spot for the hole is. Looking under the dash there's a lot of plastic in the way. Thanks for any tips

if its not a 6 speed then you can drill where the master cylinder would be. If it is a six speed there is still a good spot under the steering column, just cut some of that padding away. But what i would do since the original battery was located on the passenger side is run the wire into the factory grommet and into the car, that way there is no drilling and already a safe spot.

I'll try to run them both on the passenger side, thanks for the advice
