ACDelco battery negative cable Gold 2SD33XA (88864182) — copper conductor, weather‑resistant insulation

ACDelco Gold 2SD33XA (88864182) is a direct-fit battery negative cable built from high-conductivity copper with a cast lead terminal and weather-resistant insulation for reliable ground connections.

This ACDelco replacement cable is engineered for dependable electrical transfer and corrosion resistance under the hood. It matches factory fit and routing for many vehicles, making it a straightforward swap when a battery negative lead shows wear, corrosion, or poor conductivity. Manufactured to ACDelco’s aftermarket standards, the part balances long-term durability with consistent electrical performance.

How does this cable improve electrical grounding in my vehicle?

The cable uses solid copper conductors for low resistance, ensuring a strong ground path from battery to chassis. A cast lead terminal at the battery end provides a secure, conductive clamp that resists movement and maintains contact under vibration.

• Copper conductor reduces voltage drop and heat buildup.
• Cast lead terminal delivers a stable, corrosion-tolerant connection.
• Overlapped casting and insulation increase protection at the joint.

Will this cable withstand harsh under-hood conditions?

Yes — the outer layer is a cross-linked synthetic rubber insulator designed to resist oil, heat, and abrasion typical in engine bays. The overlapping of the cast terminal and cable insulation further guards the transition point from moisture and contaminants.

• Cross-linked rubber resists high temperatures and chemical exposure.
• Overlapped terminal casting limits corrosion entry at the clamp.
• Durable jacket minimizes chafing where the cable is routed.

Is this an easy replacement for the original part?

ACDelco designs this cable to meet original equipment fit, form, and function so it installs with standard hand tools and the same routing as the factory line. That makes it suitable for DIY swaps or quicker shop installations without additional modifications.

• Direct-fit sizing for straightforward installation and routing.
• Standard battery terminal style works with common battery posts.
• Compatibility with many vehicle applications reduces need for adapters.

What maintenance or safety steps should I follow when replacing a negative cable?

Always disconnect the negative terminal first and reconnect it last to reduce short risk. Inspect mating surfaces and battery posts; clean corrosion before installing the new cable, and tighten the clamp to manufacturer torque specs for reliable contact.

• Disconnect negative terminal before any battery work.
• Clean battery posts and terminal surfaces for best conductivity.
• Observe safety warnings: lead-containing components — wash hands after handling.

Who is this for: Automotive owners and technicians who need a reliable, OEM-style battery negative cable replacement that emphasizes conductivity and resistance to under-hood wear. It’s appropriate for drivers looking for a durable aftermarket part from a recognized brand, or service shops replacing worn, corroded, or damaged negative battery leads during routine battery or electrical repairs.
