so what your (not you in general) gonna buy a socket from the store with a short pig tail on it and splice it in? thats a lame *** way of doing it if ya ask me..
i bought these plus and sockets many years before any after market wiring kit was available,,,they are replacement parts,,, i donot know for sure,,but i would think none of the kits have the socket or plugs attached,,,all will have to be soldered,, at some point together, weather you use old or new sockets with a new wire harness,,,
