That sound great . Can you email me a pic if poss. [email protected].I have one off a UK 1975 CB250G5 (same loom) .. I bought it from a member on another Honda forum for 25 GBP plus post but I have sold the bike now and never fitted it, so therefore surplus to requirements. It's unmolested and includes the fuse box. If you are interested you can have it for what it 'owes' me i.e £25 plus post (bike had done 15k it came off).
Part no. is 32100-369-000 BTW
