Furukawa connectors are common in Honda (Civic, Accord, CR-V, Jazz), Nissan (Qashqai, X-Trail, Micra), and Mitsubishi (Outlander, ASX, Lancer) vehicles. The connector housing may also be stamped with the DJ cross-reference number (DJ7121Y-2.3). If the part number is not visible, measure the terminal pitch — 2.3mm is noticeably larger than 1.5mm but smaller than 2.8mm.\u003c\/p\u003e\n\n\u003ch3\u003eQ: What is the difference between FW-C-12M-B and FW-C-12F-B?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eFW-C-12M-B\u003c\/strong\u003e is the male plug — it has pin terminals that insert into the female socket. \u003cstrong\u003eFW-C-12F-B\u003c\/strong\u003e is the female socket — it has socket terminals that accept the male pins. In a connector pair, the male plug connects to the wiring harness side and the female socket connects to the component (ECU, sensor, actuator) side — or vice versa depending on the specific application. Always verify the gender of your original connector before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eQ: Can I use FW-C-12M-B and FW-C-12F-B as a matched pair for a custom wiring harness?\u003c\/h3\u003e\n\u003cp\u003eYes — the FW-C-12M-B and FW-C-12F-B are a matched connector pair that mate together. They can be used to create a new 12-pin disconnect point in a custom wiring harness, add a service connector for easy component removal, or replace a damaged connector pair in an existing harness. Use 2.3mm Furukawa-compatible crimp terminals and a precision ratchet crimper for reliable terminal connections.\u003c\/p\u003e","brand":"Keszoox","offers":[{"title":"15cm wire","offer_id":47394035826923,"sku":"14:200003699#15cm wire","price":34.56,"currency_code":"USD","in_stock":true},{"title":"Male Connector Set","offer_id":47394035859691,"sku":"14:200004889#Male Connector Set","price":16.5,"currency_code":"USD","in_stock":true},{"title":"15cm wire 1","offer_id":47394035892459,"sku":"14:200004891#15cm wire","price":34.8,"currency_code":"USD","in_stock":true},{"title":"Female Connector Set","offer_id":47394035925227,"sku":"14:200004890#Female Connector Set","price":16.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/1005\/8731\/files\/12-pin-furukawa-black-connector-main.webp?v=1770361469","url":"https:\/\/keszoox.com\/products\/1-set-fw-c-12m-b-fw-c-12f-b-12pin-dj7121y-2-3-11-dj7121y-2-3-21-furukawa-black-female-male-connector","provider":"Keszoox","version":"1.0","type":"link"}
