My 06 TJ has a rubber plug just under the main wiring cluster coming through the firewall. I just ran the wires through this hole and plugged it back up. Hope that helps!
Any wiring harness that passes through the firewall in a Cirrus will use a grommet. If you are adding a wire, snake the wire with the harness bundle to pass through the firewall.
It is recommended to locate an existing grommet or use a rubber firewall plug to pass the amp power wire through the firewall of a 2005 Toyota Hilux. Make sure to avoid any sharp edges that could potentially damage the wire. It's also important to seal the hole properly to prevent water and debris from entering the cabin.
Through the wire harness bulkhead on the drivers side firewall.
To run a power wire through the firewall on a 2002 Saturn L200, locate an existing grommet or firewall penetration point that is not in use. Ensure it is a safe and secure passage point before passing the wire through. Be sure to seal the opening properly after routing the wire to prevent water or debris from entering the cabin.
On my '01 GA, there's a rubber septum under the carpet near the brake petal that you can get through to pass a cable through to the engine compartment.
There should be a location where you can go through the firewall where other wires are already there. Piggy back on that hole. If not then just drill a hole through the firewall, being very careful not to drill into any wiring or components. Insert a rubber grommet in the hole to protect the wire, and then the wire.
put a wire through it
it can easily pass through a wire a conductor or a battery
either drill a hloe thru firewall or use a screwdriver to make a hole in a rubber grommet that is already in firewall. then push wire thru . u dont need a big screwdriver and the rubber will close back around the wire
There is a drain tube that goes through the firewall and comes out under the car. Use a piece of wire to stick up there and unclog it, water will run out when you have got it.
The lower right side of the firewall. There is a wire harness grommet already there it's tight but I got a 0 gauge wire through by greasing the wire first.
