* Engine Compartment: A significant portion of the harness is located within the engine bay, running along the firewall, connecting to the engine control module (ECM), sensors, and other components. Look closely around the firewall, near the battery, and along the sides of the engine.
* Dash/Instrument Panel: A large portion of the interior harness is behind the dashboard. Accessing this requires removing parts of the dash, and is generally only done for major repairs or installations.
* Under the Carpeting: Wiring runs under the carpeting of the floorboard to power various components like seats, power windows, and the radio. This is usually only accessed for repairs to the specific circuits.
* Trunk/Rear Area: Wiring for taillights, trunk release, and other rear components runs through the trunk area.
To find a *specific* wire: You need to know what component that wire leads to. Consult a wiring diagram specific to your 2000 Dodge Avenger's model (there were several trims). These diagrams show the wire's path and color codes. You can often find these diagrams online through repair manuals or automotive forums.
Without knowing the specific wire or component you're looking for, it's impossible to give a more precise location. Be very cautious when working with the wiring harness, as damage can be difficult and expensive to repair.
