Unsealed 7.8mm – When to Use This Connector
The unsealed 7282-3020 / 7283-3020 is designed for protected, dry locations – inside engine bay fuse boxes, within enclosed relay panels, or in battery compartments where direct water exposure is not expected. For exposed underbody or outdoor high-current connections, use the waterproof sealed 7.8mm variant (6189-0172 or equivalent).
High-Current Connector Selection Guide
- 2.8mm Metri-Pack 280: 13A/pin – injectors, sensors
- 6.3mm Faston / Metri-Pack 630: 20A/pin – relays, fans
- 7.8mm Yazaki (this connector): 30A/pin – main power, alternator, battery
Frequently Asked Questions
Q: Are 7282-3020 and 7283-3020 a matched pair?
A: Yes. 7282-3020 is the male plug; 7283-3020 is the female socket. In the Yazaki 7282/7283 series, the 7282 prefix always denotes the male plug and 7283 always denotes the female socket.
Q: What wire gauge should I use for a 30A circuit?
A: For 30A continuous load, use a minimum of 10 AWG (6.0 mm²) wire. For 20–25A circuits, 12 AWG (4.0 mm²) is acceptable. Undersized wire causes voltage drop and connector overheating at high current loads.
Q: What crimping tool is needed for 7.8mm Yazaki terminals?
A: Use a heavy-duty ratchet crimper rated for 10–12 AWG (4.0–6.0 mm²) – such as the Hozan P-706 heavy version or Engineer PA-20. Standard automotive crimpers are too small for 7.8mm terminals.
