The switch is easy to install and can be replaced without needing to remove the distributor or other major engine components. Simply disconnect the battery negative terminal, remove the old switch, install the new one, and reconnect the battery terminal.

This Motorcraft NOS part comes packaged in a protective, anti-static bag to ensure the switch remains in pristine condition during transportation and storage. The part number E0TZ-7E440-A is printed on the packaging and the switch itself for easy identification and ordering.

The Motorcraft SW-1591 NOS Ignition Spark Advance Switch E0TZ-7E440-A is a part used in Ford vehicles, specifically in 1980 Broncos, for controlling the ignition system's spark advance. Here are some potential pros and cons of buying this part:

1. OEM (Original Equipment Manufacturer) part: This part is manufactured by Ford Motor Company, ensuring it is a direct fit and of high quality.

2. New Old Stock (NOS): Since this is a New Old Stock part, it is unused and unopened, meaning it is in its original condition and has not been previously installed or rebuilt.

1. Cost: OEM parts, especially new old stock ones, can be more expensive compared to aftermarket parts.

2. Availability: Because it is a specific part for a specific year and model, it may not be readily available at local auto parts stores and may need to be ordered online.

3. Installation: Installing the part may require some mechanical knowledge or hiring a professional mechanic.

The Motorcraft SW-1591 NOS Ignition Spark Advance Switch E0TZ-7E440-A is an excellent choice for anyone looking for a high-quality, direct-fit replacement part for their 1980 Ford Bronco.
