You are purchasing one USA made reproduction headlamp wiring harness and block for 1960 to 1969 Panheads, Shovelheads, & Servicars for Duo-Glide and Electra-Glide style "moose head" headlamps.  I believe the same block is used on later models but cloth covered wire was correct for 1969 and earlier please check your own reference material.  H-D also changed up their front wire terminal blocks in 1970 and I believe there was another revision later on which may render it impossible to use this with the provided terminals. White and black traced wire is high beam, yellow & black traced is low beam, black/white is ground.  

We also sell complete wiring harness kits, wiring clip kits, tail lamp harnesses, and wired handlebar switches for just about every model from 1916-1969..
