Detailed Description

Standard Ignition S-2066 is engineered for rear light harness repair on GM platforms where the original connector has heat damage, corrosion, broken locking features, or terminal wear. This connector supports a clean repair approach by replacing the damaged connector only, helping restore proper rear lamp circuit continuity on vehicles such as the Chevrolet Colorado, Silverado 1500, Tahoe, Avalanche, Suburban 2500, GMC Canyon, Yukon, Yukon XL 1500, Yukon XL 2500, and 2012 Buick LaCrosse. This part cross-references OE-style numbers such as 13504593 and EC1712 for the same application.

The S-2066 part number is built with high-grade conductive metals and a polyamide resin housing to support long service life and stable electrical performance. Standard Ignition S-2066 is a practical choice when diagnosing rear lighting faults on 2004-2012 Chevrolet Colorado and GMC Canyon models, or 2009-2012 Chevrolet Silverado 1500 and Tahoe applications.

Common Repair Uses

• Broken or melted rear light connector housing
• Corroded or loose terminal contact at the rear lamp harness
• Intermittent tail lamp, stop lamp, or rear signal operation
• Damaged wiring connection at the rear lighting assembly
• Failed connector fitment after previous electrical repair

Installation Notes and Tips

Verify connector shape, terminal style, and wire count against the original rear light harness before installation. Match the existing circuit layout carefully and inspect the mating terminals for heat damage or corrosion before reconnecting. Confirm proper electrical function after installation on the rear lighting circuit.

Quality Assurance

Standard Ignition tests these electrical connectors for proper mechanical and electrical fit, form, and function. The connector uses copper alloy, brass, and phosphor bronze terminals with a polyamide resin housing to support consistent performance in demanding automotive electrical repairs.
