How find out find wich relay fuse is bad for tail lights

Hello,

The parking light fuse is located under the hood in the power distribution center fuse box (see diagram below).
It should be fuse number 11, which is a 15A fuse.

If the fuse if good, then the issue is likely a bad wire. Which will require tracing of the wires to find the short or a bad ground.
