Nothing is firm-fixed from Ford, I just found another style of tag for the 65-66 console main harness, a red marker about 1/2 inch wide and 3/4 inch long with the part number "C5ZB" (line one, large font), "13B711-A" (second line, smaller font - Note, no "dash" between lines) and "FoMoCo" script logo in an oval with a tiny circle "R" trademark in the lower right. It appears to be a tape (think 3M Scotch) vs paper. I think that may be a later version by the logo. The source of the harness (year, month, plant) is unknown. When I get my camera back from my kid, I'll take some pictures.
