    Remote Power

    I have heard of using a frame rail under the car, rather than routing it through the cabin. You may have to cut a hole in the frame rail if you go that way; I wouldn't want to cut a very big one! An oh, when you cut a hole, spray paint the edges of your cut to avoid rusting.

    Also, I have seen where people have used an existing boot? grommet? that is in the firewall around an existing penetration; cutting a hole in the "boot" and passing the new wire through it.

    I suggest using polyethylene tubing as a conduit and fasten it to the side of a frame rail.

    If you need to enter the trunk from the outside, look for rubber bungs that are usually in the lowest part of the trunk, used to drain water when flooded inside. Cut a hole in the rubber bung and pass your mini-conduit through.

    Hope any of that helps.

    In my 02 i ran the power cable through a rubber grommet that is right behind the clutch pedal. mine already had a hole in it but it would be easy to cut a hole slightly smaller than the cable to tightly seal the hole.

    When you ran it through did it interfere with your clutch at all or will the clutch still have full range of motion?

    It did not interfere at all.
    I still have all my clutch functionality.
    I just fed it around/through existing wires to have it out of the way of everything
