From 1954 - 1969 there were basically NO changes in wiring scheme, all models used 3 way rather than 5 way switches common today. Capacitor type - up till '62 paper caps, then round ceramics after that. Cloth insulated wire replaced by plastic in late'67/early '68. Pickups were "black bottom" type through 1964, switched at that point to "gray bottom" with gray cardboard/fiberboard bottom, the latter always initialed/dated.
That's all.
