How hard is the passing lamp install on an 08 FB? I just picked up a new set off of EBayand I'm inclined to do it myself instead of handing it over to the dealer. I do have the(unopened as of now)Service Manual for it but not an Electrical manual. The FatBoy is my first cycle since the 70's so I am pretty new at wrenching on one...Thanx for any help you guys can give me...
