    quick question about firewall

    Trying to find a good sized hole on a 09 srx 4wd on the passenger side firewall near the battery. Anyone know of a good whole or where I should be able to drill one without alot of issue. Looking to get fit a run of 0 gauge wire.

    Best place is to check your local installers

    Infront of the brake pedal is a rubber boot on the firewall. Its where the main wire harness runs. But to access it from the outside you have to loosen the coolant resovoir to get your arm in there. Best way is to push the wire through is from the inside an out

    I used this method to run cable for my brake controller. Once you push the wire through liberally from the inside, you might be able to grab it with a long set of pliers.(or similar)
