Wires from the front and rear derailleurs, cockpit area, and battery all plug into the 4-port SM-JC40 junction, which integrates the inputs for full connectivity. Remember that a single wire is run from the cockpit junction box down to the SM-JC41, as the cockpit junction A integrates the shifters.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch5\u003eFeatures \u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e4-port junction box for internally wired Di2 e-Tube set-ups; integrates the ported wires\u003c\/li\u003e\n\u003cli\u003eCan connect e-Tube wires from: front and rear Di2 derailleurs, cockpit junction, battery\u003c\/li\u003e\n\u003cli\u003eSit inside lower downtube\/BB area on most frame designs\u003c\/li\u003e\n\u003cli\u003eComposite material; sealed\u003c\/li\u003e\n\u003cli\u003eColor: Black\u003c\/li\u003e\n\u003cli\u003eWeight: 5 grams\u003c\/li\u003e\n\u003cli\u003eShimano part # ISMJC41\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"Default Title","offer_id":43697505140907,"sku":"ISMJC41","price":32.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/9424\/0427\/files\/112357-2.jpg?v=1711949423","url":"https:\/\/ascent-testing.myshopify.com\/products\/shimano-jc41-di2-internal-frame-junction-box-4-port","provider":"Master Store","version":"1.0","type":"link"}
