i just replaced the turn signal module on my 2006 fxst. the parts guy at harley said i would have to program the replacement module to learn the password. my motorcycle does not have security. after i replaced the turn signal module it will crank and run with no problem. does the module still need to be programmed?

Generally they have to be programmed with the security using this procedure.

They have to communicate with the ecm after a replacement. Being you don't have a problem without the security and it runs, leave it alone.
