EDS Battery Terminal Set for Toyota/Scion – Positive 18mm & Negative 16mm with M8 Nuts, OE-fit

EDS 90982-05054 & 90982-06059 is a two-piece replacement battery terminal set—positive (18mm) and negative (16mm) with M8 nuts—made to restore secure, OE-compatible electrical connections on many Toyota and Scion models.

If your vehicle shows signs of weak starting, dim lights, or visible corrosion at the battery posts, worn terminals are a common culprit. This EDS terminal set is manufactured to meet original-equipment dimensions so it fits directly where the factory parts do. The pair includes distinct-size clamps for positive and negative posts and comes with M8 fastening nuts to keep connections tight and stable during normal driving conditions.

Which vehicles will these terminals fit?

These terminals were designed as compatible replacements for a broad list of Toyota and Scion models across multiple years. They match OE sizing and geometry so the swap is typically plug-and-play for models listed by manufacturers and parts catalogs.

• Common fits include Corolla, Camry, Highlander, Tacoma, Tundra, and multiple Lexus/Scion derivatives.
• Model year ranges include many vehicles from mid-2000s through the 2020s—check specific fitment for exact years.
• Both negative (16mm) and positive (18mm) post sizes are covered for the listed applications.

How do these terminals improve electrical reliability?

Replacing corroded or loose battery terminals restores consistent metal-to-metal contact, which reduces voltage drop and prevents intermittent faults. The EDS set is produced to OE tolerances so it aligns with factory wiring and cable clamps for dependable conductivity.

• New metal connection surfaces reduce resistance compared to corroded OEM parts.
• M8 nuts provide firm clamping force to prevent post movement under vibration.
• Direct-fit design minimizes time spent modifying or adapting parts.

What should I expect during installation?

Installation is straightforward for anyone comfortable with basic battery work: disconnect the old terminals, clean the battery posts if needed, and bolt the new clamps in place. No special tools are required beyond common hand tools and safety precautions when working with a vehicle battery.

• Use wrench/socket set for M8 nuts and standard terminal bolt sizes.
• Disconnect negative terminal first, then positive; reverse when reattaching.
• Inspect battery posts and cables, trim or replace frayed cable ends if present.

Are these genuine OE-quality parts and what materials are used?

EDS supplies these terminals to match OE specifications, produced with materials and machining intended to deliver long-term durability. While not branded as factory units, they are engineered for the same fit, function, and mounting points as original components.

• Manufactured to meet or exceed original equipment dimensional standards.
• Metallic contact surfaces designed for low-resistance electrical flow.
• Supplied as a complete positive and negative terminal set with M8 nuts.

Who is this for: This EDS terminal set is aimed at owners or technicians working on Toyota and Scion vehicles who need a direct-fit battery terminal replacement. It suits DIY mechanics replacing corroded or damaged terminals, fleet maintenance shops performing routine electrical repairs, and anyone restoring reliable battery connections without modifying factory wiring. Always confirm model-year compatibility with your vehicle’s part references before purchase.
