Hi guys. First post on clublexus and looking forward to my time here.

I have a 3gs and trying to wire in a second battery for audio and whatnot.
I have a battery isolator that requires a 12v source only in the on/running position.
(Not to be confused with ACC on or Constant 12v).

Any ideas on a good source to tap into? The preferred location would be the engine bay but im open to suggestions.

Thanks!
