To find it, you'll need to do some detective work:
* Visual Inspection: Carefully examine the area around where the cigarette lighter *would* be (if it were factory-equipped). Look for wires or connectors that seem unused or potentially related to a power source. Often, these wires are tucked behind the dash panel, under the radio, or near the fuse box.
* Fuse Box Check: Your owner's manual (if you have it) should show a fuse box diagram. Look for a fuse labeled "cigarette lighter," "power outlet," or something similar. Tracing the wire from that fuse is the most reliable method.
* Wiring Diagram: A wiring diagram specific to your 1985 Nissan Pulsar NX is your best bet. These can sometimes be found online through forums dedicated to classic Nissan cars, or through a repair manual. The diagram will show you exactly where the wire is routed.
* Removal of Dash Panels: This is a last resort and should only be done if you are comfortable with car disassembly. Be careful not to damage any components when removing panels.
Important Safety Note: Always disconnect the negative battery terminal before working with car wiring to prevent accidental shorts or electrical shock.
