Verify the male housing part number on your vehicle harness before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Can I use this connector for a 30A circuit?\u003c\/strong\u003e\u003cbr\u003eA: Yes. The 7.8mm Yazaki series is rated for 30A per pin. Ensure the wire gauge is appropriate – 30A continuous load requires a minimum of 12 AWG (3.0 mm²) wire to prevent voltage drop and overheating.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: What crimping tool is needed for 7.8mm Yazaki terminals?\u003c\/strong\u003e\u003cbr\u003eA: Use a ratchet crimper rated for large-gauge terminals (10–14 AWG \/ 2.5–6.0 mm²). The Hozan P-706 or equivalent heavy-duty ratchet crimper is recommended. Do not use standard automotive crimpers – they are too small for 7.8mm terminals.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Is this connector suitable for marine applications?\u003c\/strong\u003e\u003cbr\u003eA: Yes. The IP68 waterproof rating makes the 6189-0172 suitable for marine, outdoor, and underbody applications where continuous water exposure is expected.\u003c\/p\u003e\u003ch3\u003ePackage Contents\u003c\/h3\u003e\u003cp\u003e1 × 2-Pin Female Connector (6189-0172) with wire and terminal insert\u003c\/p\u003e","brand":"Cable Parts Online","offers":[{"title":"2P \/ Female with Wire \/ China Mainland|Line Connector|10 sets","offer_id":47844186849525,"sku":"14:200004889#Female with Wire;200001249:202408829#10 sets;200007763:201336100;200497261:200000932;462:203053809","price":149.85,"currency_code":"USD","in_stock":true},{"title":"2P \/ Female with Wire \/ China Mainland|Line Connector|3 sets","offer_id":47844186882293,"sku":"14:200004889#Female with Wire;200001249:202408832#3 sets;200007763:201336100;200497261:200000932;462:203053809","price":45.0,"currency_code":"USD","in_stock":true},{"title":"2P \/ Female with Wire \/ China Mainland|Line Connector|1 set","offer_id":47844186915061,"sku":"14:200004889#Female with Wire;200001249:202408830#1 set;200007763:201336100;200497261:200000932;462:203053809","price":15.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0732\/3494\/0149\/files\/S1cfe31cc74494dab806048390e4240ecw.webp?v=1773810032","url":"https:\/\/www.csldmcml.com\/products\/2-pin-6189-0172-waterproof-7-8mm-female-connector-motorcycle","provider":"Cable Parts Online","version":"1.0","type":"link"}
