    I am wanting to install a (ham) tranceiver in my 02 Forester and need
    to route the power cable directly to the battery. Is there an access
    point in the firewall somewhere to get the cable from inside the car to
    the engine area?

    I found a route on my 04 XT on the passenger's side near the middle.
    There's a black tube that goes through and I just pushed the wire
    through that same grommet. I started from the engine compartment and
    then pulled from inside the car once I could see where it came through.
    From there it's close and easy to get to the console area.

    Steering shaft grommet works, slit it with razor blade and silicone it shut.
    I recommend against going straight to the battery because the gasses there
    will turn the wire green for the first few CM past the battery. High
    resistance low amps.
    I go to the starter positive and don't have to cut the power cord every
    year. I know that's not what QST says but hey, they are amateurs also.

    hmmm. .... sounds cool. I am a amateur-ham wannabe, do you mind tell me what
    you can use your ham radio on car for?

    and can't you just think about the car plug-in?

    Hi Spudzzz, All!

    I picked up 12VDC for the ICOM dual-band radio in my car (an older
    Subaru) by splicing into the large white wire that supplies accessory
    power and whatnot for the fuse box. Get a good chassis ground as close
    to the xcvr as possible.
    If you do run a wire to the battery, route it carefully away from heat
    sources, and sharp edges. Use an awl to poke a hole in the grommet
    where the wiring bundle penetrates the firewall, and feed the wire
    thru that. Be sure to locate the fuse for this lead as close to the
    battery as possible.
    I use a roof-mount antenna connection, and haven't had problems with
    RF upsetting the cars electronics. This can sometimes be a problem
    with mag-mount antennas, or other antennas that don't get a good
    ground at the antenna base. In my truck, (mag-mounted whip antenna) I
    (mostly) fixed this by sliding several ferrite cores over the antenna
    coax right where it connects to the rig.
    Hope this is helpful.

    ByeBye! S.
