I've got a little 12 foot alum. boat with 6 hp engine on a light trailer that pulls easily with my Toyota RAV 4. <br /><br />Wiring installed on towing vehicle as per instructions for single bulb tail lights won't work for turn sigs however; the RAV has seperate signal lights. <br /><br />I've heard of an adapter that's necessary to accomodate this arrangement. Is it necessary or is there a way to wire it in directly so I can have turn signals too?<br /><br />CHRIS
