500Pcs Connector Terminal Pin Wire Harness Pins Automotive

AYZAR 500-piece connector terminal kit bundles six pin sizes, 240 wire seals and a removal tool to build or repair automotive, motorcycle and ATV wiring reliably.

This all-in-one assortment organizes the most commonly used terminal pins and compatible seals for aftermarket and repair work. The kit groups 260 tin-plated copper pins across six diameters with 240 silicone/PE seals and a small removal kit, so you can crimp, solder or replace contacts without hunting for individual parts. Designed for DIYers, mechanics and electrical hobbyists, the set aims to reduce downtime and keep multiple connector types on hand.

Which pin sizes are included and when should I use each?

The kit contains pins in 1.0, 1.5, 1.8, 2.2, 2.8 and 3.5 mm series to cover a broad range of wire gauges and connector housings found on cars, motorcycles and ATVs. Smaller pins suit signal and low-current circuits; larger pins are for power feeds and heavier loads. Keep matched seals and housings available to maintain moisture resistance and strain relief.

• 1.0 mm — small signal wires, sensors and instrument connectors
• 1.5 mm — general-purpose signal lines and thin automotive wires
• 1.8 mm — medium gauge harness connections
• 2.2 mm — common for power taps and switches
• 2.8 mm — thicker power or ground conductors
• 3.5 mm — heavy feed lines and higher-current circuits

How durable and conductive are these terminal pins?

Each pin is made from tin-plated copper to combine good electrical conductivity with corrosion resistance. The tinning protects contact surfaces from oxidation and improves solderability, while the copper core maintains low resistance. Proper crimping or soldering yields a dependable mechanical and electrical junction for vehicle environments.

• Tinned copper for corrosion protection and improved soldering
• Suitable for both crimp and solder terminations
• Robust metal core to reduce voltage drop in power circuits

What else comes in the box and how does the removal kit help?

Aside from 260 terminal pins and 240 wire seals, the kit includes a compact removal tool set to extract terminals from connector housings without damage. The tools let you release locking tangs and pull pins cleanly so you can reuse housings or replace only the faulty contact. Everything is packed in a compartmentalized box for quick selection on the bench or in the field.

• 240 compatible wire seals for moisture and vibration protection
• Terminal removal tools for safe, repeatable extraction
• Compartment box sorted by size to speed workflow

Can I use these pins across different vehicles and projects?

The assortment is intended as a versatile starter kit for many automotive, motorcycle, marine and small-engine wiring tasks. With multiple pin sizes and seals, it fits a variety of connector housings and wire gauges used in aftermarket repairs and custom harness fabrication. Always match pin size and seal type to the connector housing and wire to ensure fit and electrical integrity.

• Works for cars, motorcycles, ATVs, boats and DIY electronics
• Mix-and-match sizes let you repair diverse connectors on one job
• Useful for prototyping, repair, and on-vehicle splicing

Who is this for: This AYZAR kit is aimed at automotive technicians, motorcycle mechanics, electrical hobbyists and DIYers who need a compact, mixed assortment of reliable terminal pins and seals. If you build or repair wiring harnesses, restore vintage connectors, or keep a mobile repair kit for roadside fixes, the boxed assortment reduces parts hunting and speeds repairs while offering corrosion-resistant contacts for long-term performance.
