Stop in for a cup of coffee

Question one of the taillight bezels had a taillight wire wrapped in a brownish green looking unknown material. Even had a old white tag with a number, maybe a part number??
Almost certainly.
The p/n for the instrument harness is by the hi/low switch. Just starting to fall unravel now but held up well all considering.

When I went back to get the doors today, I found four more taillights sockets with the same wrap, all in great shape.
What color was the old stuff?? Anyone know??
I'll post a pic later.
I can see what's left of mine, but that area has been repaired twice from rear end hits.
Also the wire coverings have been falling apart since before I bought it.
It probably lived under a carport and the sun baked the trunk.
Paint back there was so thin that the primer showed through at the stripe. (stripes were painted before the body color in case anyone is curious)
