Your question is incomplete. You asked a question that is like, "Where is the hole in the Swiss cheese?". There are usually several holes and each hole has a specific item or loom of items running through it. For example, the speedometer cable may have a hole in the firewall for itself or the A/C lines have holes in the firewall for their passage. BETTER QUESTION: WHERE IS THE HOLE IN THE FIREWALL FOR THE _________________?

If you are talking about a 1998-2005 Passat there is a bleed hole in the cooling system for this purpose. The heater coolant lines pass through the second firewall remove the clamps on the lines and pull them toward the front of the car about an inch. One of the lines has a little hole for bleeding the system.
There are several firewall holes.The firewall is the wall that divides the engine from the passanger compartment.Under the windshield.
On a 2002 Lincoln LS : The engine coolant reservoir is in the engine compartment , on the drivers side , by the firewall ( you can see the cap on the reservoir through a hole in some kind of trim according to a drawing I was looking at )
I was looking at a picture in the 2004 Lincoln LS owners manual and it shows that the engine coolant reservoir is located on the drivers side of the engine compartment next to the firewall ( you can see the cap for the reservoir through a hole in some kind of panel )
k hole
On a 2002 Lincoln LS : The degas bottle ( engine coolant reservoir with the pressure cap / radiator cap screwed on the top ) is located in the engine compartment , near the firewall , on the drivers side of the engine compartment ( you will see the " cap " through a hole in a piece of " trim "
On a 2002 Lincoln LS : The engine coolant reservoir has the pressure cap / radiator cap screwed on top of it , so it is called a degas bottle * it is located in the engine compartment , on the drivers side , near the firewall ( there is a hole through the " trim " to gain access to the cap )
If you cant find an openening large enough then you can always drill a hole and place a grommet in the hole and then run the wire through the grommet. Hope this helps.
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.
On a 2000 Lincoln LS : The thread on cap on the engine coolant reservoir is the pressure cap / radiator cap * the engine coolant reservoir is in the engine compartment , on the drivers side of the engine compartment , next to the firewall , you can see the cap through a hole in the " trim "
