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":48086376120472,"sku":"17YTM","price":999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0564\/0867\/0360\/files\/wiring-specialties-wrs-prolsxg4-e30-main.png?v=1771216729","url":"https:\/\/frsport.com\/products\/bmw-e30-ls2-wiring-harnesss","provider":"FR SPORT","version":"1.0","type":"link"}
