Orange and White wire bad?

Went to install a rear light under the rear bumper on the #6 switch tonight and had a gremlin. #6 Orange and yellow to the brown and white under the hood and the white and orange to the brown and white under the dash but had no power to the pig tail under the rear cargo area. Tested it with a a meter and very odd. I had power under the hood and under the dash but the white and orange was bad. I had to run a new wire from the brown and white under the dash to the rear bumper and bypass the white and orange, it was very easy but very odd. And who the he’ll put the rear cargo white and orange by the B pillar under the cover. Works now but cost me a good hour trusting the cord wiring. Unless I did something wrong.
