If the Option exists to ADD the unit on the harness page for your swap, then you need it for proper speedo operation. Please note that some transmissions (350z, BMW ZF and S15 Silvia for example) do not have a speed sensor and will require a non-harness based solution like a GPS speedo.\u003c\/li\u003e\n\u003cli\u003ePlug-n-Play vs Universal\u003c\/li\u003e\n\u003cli\u003ePlug-n-Play harnesses connect to your car's underhood fuse box for power and to connectors under the dash for gauges etc. Universal harnesses do not need an underhood fusebox to connect to and the wiring for gauges and warning lights is provided as a 'flying lead' which are bare wires labeled with their function.\u003c\/li\u003e\n\u003cli\u003eRight Hand Drive (RHD) Conversions\u003c\/li\u003e\n\u003cli\u003eIf you used ALL the stock LHD chassis connectors for your RHD swap, order the LHD version of the harness.

Typically this positive battery cable also powers up the main under hood fusebox, which runs many of the non-engine items on your car like interior lights, dash power and headlights\/taillights. Please make sure you have prepared for this as each install is different.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Wiring Specialties","offers":[{"title":"Default Title","offer_id":48086494347416,"sku":"8Q8WV","price":999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0564\/0867\/0360\/files\/rx7_3__20894.1478834539__56631.1619694515.jpg?v=1769753603","url":"https:\/\/frsport.com\/products\/rx7-ls3-58x-wiring-harness","provider":"FR SPORT","version":"1.0","type":"link"}
