Since my back is out and I can't do anything really useful, I decided to start replicating wire labels for my SJ fastback (see sig).
I've noticed a lot of interesting things:
The instrument panel wires have a green FoMoCo label with part numbers and a white assembly label.
The FoMoCo tag is fairly narrow (0.725 or less), so the C7ZB is on one line, the part number of 10B942 is on another.
The assembly label is slightly narrower at about 0.625 and reads:
JAN
DAY
TSX
in a repeating pattern. The text is not straight and could be a stamp. Not sure what DAY means, but it might be the assembler's initials. JAN appears to be for January, since all other items on the back of the dash panel also read 01 or A.
I only mention the instrument harness as it's very well preserved and original.
The main under dash harness is red tape with a yellow label over the top. The assembly label is within an inch of the Ford part number tag. both labels are about the width of the instrument panel labels.
The tail light harness on my 67 fastback was red but has disintegrated and cannot be read. However, what is left is the same width as the instrument panel harness Ford id label.
When I replicate this label it will also be red, have C7ZB on one line and 14405-A on the next.
If I follow the pattern of the instrument panel label for the tail light harness it should read:
TSX
C7ZB
14405-A
FoMoCo in a rounded box
repeat the pattern.
A parts car I have that is within a few thousand VINs at SJ as well and has this label format for the tail light harness, but in white:
S.X. -A
C7ZB
14405-A
FoMoCo in a rounded box
repeat the pattern.
I have found no assemblers tape on any of my tail light panel harnesses, but they are not unmolested like the Paperback Writer harness.
