hi there. ive got an alpine headunit which id like to fit to the lexus. bought a fascia and that fits perfectly. so went down to halfords and thought id be a clever **** and buy the toyota adaptor lead, got home tried to fit it, fitted the headunit but wouldnt fit the car. got onto ebay and found one of these: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...em=150333199627 thought PERFECT, turned up today, exactly the same plugs as the one from halfords. on reading the ebay listing it says it fits non amplified is200's only. im baffled as i didnt think mine had an amp as the sound quality is rather poor!! would this all suggest different? and if so what lead do i need now??
