WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2003 Mercury Sable, 2003 Mercury Mountaineer, 2003 Mercury Marauder, 2003 Mercury Grand Marquis, and 2003 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.

Some engine control hardware has gold plated terminals on connectors and mating harness connectors to improve electrical stability for low current draw circuits and to enhance corrosion resistance. OBD-II components equipped with gold terminals will vary by vehicle application.
