Seamaka 432pc Automotive Electrical Connector Kit — 2.8mm multi-pin housings & ratchet crimper

Seamaka’s 432-piece automotive electrical connector kit supplies insulated housings, tin-plated pins, and a ratchet crimping tool to quickly assemble reliable 2.8mm multi-pin vehicle connections. This compact organizer box is built for DIY mechanics, electricians, and fleet technicians who need a complete set of small-form wire terminals and housings for cars, motorcycles, boats, and light vehicles. The kit groups common 2.8mm connector sizes — 2, 3, 4, 6 and 9-pin — together with female heads and a ratchet crimper so you can build or repair multi-pin plugs without hunting for individual parts.

What exactly is included in the 432-piece kit and how is it organized?

The kit contains insulated plastic housings and tin-plated copper pin terminals sized for 2.8mm connections, plus a ratcheting crimper and a clear storage box. Parts are pre-counted and stored in compartments so you can find the right housing and matching pin quickly.

• 2-pin housings: 12 pairs; 3-pin: 10 pairs; 4-pin: 8 pairs
• 6-pin: 6 pairs; 9-pin: 5 pairs; female heads: 6 pieces
• 350 pin terminals (tin-plated copper) plus 1 ratchet crimping tool
• Transparent plastic organizer for convenient access and storage

How do these connectors perform and what materials are used?

Housings are made from insulating plastic that resists abrasion and everyday vibration, while the male/female pins are tin-plated copper to improve conductivity and corrosion resistance. The ratchet crimper gives consistent compression on each terminal for a secure mechanical and electrical joint.

• Insulating plastic housings for durability and safety
• Tin-plated copper pins for better conductivity and rust protection
• Ratchet crimp tool ensures consistent terminal compression
• Terminal width and pin size optimized at 2.8mm for common automotive circuits

Where and when should I use this connector set on a vehicle?

These connectors are intended for dry and protected locations such as under dashboards, interior panels, and equipment housings rather than exposed waterproof connections. They are suitable for wiring harness repairs, adding accessories, or rebuilding small multi-pin connectors in cars, motorcycles, boats, and light utility vehicles.

• Ideal for dashboard wiring, interior lighting, and accessory taps
• Commonly used in motorcycles, cars, boats, trikes and small vehicles
• Not intended as sealed, submersible or exposed marine-saltwater connectors
• Fixed-hook housings speed assembly and prevent accidental disengagement

How will the ratchet crimping tool help my installations?

The included ratchet crimper simplifies producing repeatable crimps and releases only when a full crimp cycle is complete, reducing loose or under-crimped terminals. It’s designed to match the 2.8mm terminals in the kit so you don’t need extra tools for most jobs that use this connector family.

• Ratchet action enforces consistent crimp pressure for reliable contacts
• Compatible with the 2.8mm tin-plated pins provided in the kit
• Ergonomic handles reduce hand fatigue during bulk assembly
• Compact tool size fits into standard toolboxes or glove compartments

Who is this for? This Seamaka kit is aimed at hobbyists, automotive DIYers, electricians, and small repair shops that need a ready supply of 2.8mm multi-pin housings and terminals with a matching crimp tool. If you frequently build or repair internal vehicle wiring, restore dashboards, add aftermarket accessories, or maintain fleets of motorcycles, boats, or small vehicles, this set reduces parts sourcing time and helps produce tidy, repeatable splices and connector assemblies. It is not a sealed marine connector solution and is best used in covered or dry installations.

FAQ

Q: Are these connectors waterproof?

A: No. These are for dry or protected locations like dashboards and interior panels, not for submerged or sealed marine connections.

Q: Will the crimper work for all included pins?

A: Yes. The ratchet crimper is matched to the 2.8mm tin-plated pins supplied in the kit for reliable crimps.
