Please check notes in each part listing to ensure the Neutral Safety Switch / Range Sensor is correct for your 1978 PONTIAC FIREBIRD with a 6.6L 403 engine. AIRTEX & STANDARD MOTOR PRODUCTS are competing brands, and each brand's Neutral Safety Switch / Range Sensor may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Neutral Safety Switch / Range Sensor fits only certain 1978 PONTIAC FIREBIRD models.

Clicking a "More Info" link will display a picture and/or other details about that Neutral Safety Switch / Range Sensor in a separate window (you may need to turn off your pop-up-blocking software for this to work).

You may use your browser's Back button or click "Find More Parts" to find more Electrical-Switch & Relay parts, other PONTIAC FIREBIRD parts or parts for a different vehicle.
