Detailed Description

Standard Ignition TCA-11 is engineered for vehicles that rely on a transfer case or vacuum-operated four-wheel-drive indicator circuit. It is a practical replacement for worn or failed switches on Dodge Ram 1500, Ram 2500, Ram 3500, Jeep Cherokee, Jeep Grand Cherokee, Jeep Wrangler, and TJ models. The part number TCA-11 is also referenced in interchange listings for service matching, including Continental 49314.

This switch is built with durable materials and tested to verify both switching action and electrical performance. For technicians working on 1990-2002 Dodge and Jeep 4WD systems, the TCA-11 supports accurate indicator operation when the original switch no longer signals drivetrain engagement correctly.

Verify connector style, terminal count, and the original switch configuration before installation. This part uses a male 4-pin round connector with bullet terminals, so matching the OE connector is important for proper fit and function. The TCA-11 is commonly used on 1990-2002 Dodge Ram and Jeep 4WD systems where the indicator circuit is tied to the transfer case or vacuum control setup.
