While it is technically possible to connect a fan directly to the battery in a 1995 Dodge Neon, this is not recommended and may have several negative consequences:
* Potential Electrical Issues: By bypassing the factory wiring and controls, you may overload the electrical system, leading to damage to electrical components or even electrical fires.
* Lack of Proper Regulation: The factory cooling system for the Neon utilizes sensors and controls to regulate fan operation based on coolant temperature and other factors. Bypassing this control can result in the fan running continuously. Over-cooling can cause engine complications and additional stress on components or it possibly won't run when desired, leading to potential overheating.
* Safety and Function Issues: The original fan setup is designed to ensure correct airflow for engine cooling and temperature regulation. Altering this without proper consideration may negatively impact engine performance, fuel efficiency, emissions, and noise levels, and compromise your vehicle's overall operating safety while also voiding original vehicle manufacturer warranties for associated parts.
Using a relay (as included/used in various automotive applications) would typically help with voltage drops over longer wire runs than you might have direct to battery, and allow it's operation (if desired) with ignition key in any position/without turning car key to "on".
It's always best to follow the manufacturer's recommended electrical circuit schematics and wiring guidelines when making any modifications.
