The kit integrates a stowable 4-way flat connector near the hitch, uses heavy-duty bonded wire and tin-plated copper terminals for corrosion resistance, and includes a dust cover for protection when the plug is not in use. Installation is mostly plug-and-play, but a 12V hot lead must be run to the vehicle battery to power the trailer lighting properly.\u003c\/p\u003e\n\n\u003ch3\u003eHow easy is it to install the MECMO harness on my RAV4?\u003c\/h3\u003e\n\u003cp\u003eInstallation is intended to be straightforward: the prewired T-connector plugs into the vehicle-side harness in the rear cargo area with no splicing of factory wires. You will need to route a 12V hot lead to the battery to supply power to the trailer connector. Typical installations take under an hour for someone comfortable with basic vehicle wiring and routing under the chassis.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePrewired T-connector matches factory RAV4 harness locations.\u003c\/li\u003e\n  \u003cli\u003eIncludes instructions and a dust cover for the connector.\u003c\/li\u003e\n  \u003cli\u003eRequires running a 12V hot lead to the battery for full operation.\u003c\/li\u003e\n  \u003cli\u003eNo permanent modification to factory wiring when installed correctly.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat lighting functions does the 4-pin flat connector support?\u003c\/h3\u003e\n\u003cp\u003eThe 4-pin flat connector supplies power for tail\/marker lights, brake lights and left\/right turn signals — the standard set for basic trailer lighting. It does not carry a separate reverse or electric brake circuit; those require 5- or 7-pin setups or additional modules.

The included dust cover helps keep moisture and grime out of the connector when it’s not connected to a trailer.

This MECMO 4-pin trailer wiring harness 56434 is aimed at RAV4 and RAV4 Prime owners (2019–2024) who need a straightforward, OEM-style 4-way flat trailer connection for basic lighting. It’s a good match for drivers towing small trailers, motorcycle or bike carriers with lights, or anyone who wants a tidy, stowable connector at the hitch without modifying factory wiring. If you need trailer reverse lights, electric trailer brakes, or a multi-function connector, consider a 5- or 7-pin solution or an auxiliary module in addition to this harness.\u003c\/p\u003e\n\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this harness fit my 2020 Toyota RAV4?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — MECMO 56434 is a custom-fit 4-pin T-connector for 2019–2024 Toyota RAV4 and 2021–2024 RAV4 Prime models.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the kit power electric trailer brakes?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No — the 4-pin flat connector supports lights only; electric brakes require a 7-pin or separate brake controller wiring.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"MECMO","offers":[{"title":"Default Title","offer_id":48084082983070,"sku":"B0B635C3BY","price":82.84,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/mecmo-rav4-harness-front-view.jpg?v=1785845872","url":"https:\/\/northtrailauto.ca\/products\/mecmo-4-pin-trailer-wiring-harness-for-2019-2024-toyota-rav4-rav4-prime-custom-fit-t-connector-with-dust-cover","provider":"North Trail Auto","version":"1.0","type":"link"}
