No , I do not ... I just found that doing a Google search for Wiring Diagrams for Honda 250L's ....... There is also a place called Manuals Lib
https://www.manualslib.com/ , where you can pay and download , but you can also look at them (preview) the entire manual to make sure it has the info you need , but it will have a watermark to keep people from passing copied pages as their own till they pay for it .... I also know that you can buy them direct from Honda (go to any Honda Dealer) , they average around $50-$60 for a Factory Honda Service Manual *this is not a Clymer Manual , but a authentic Honda Factory Service Manual that ALL Honda Service Techs use**, which will give you everything related to doing any type of service on the bike from oil change to engine rebuild .... (Ken has Service Manuals here , but I did not see one for the 250L at all) ....
