Reverse Lights Dead After Backup Camera Wiring - Blown 7.5A Gauge Fuse

Electricalbeginner✓ OP Confirmed

Problem

After splicing into the reverse light wiring harness at the tail lights to install a backup camera and head unit reverse signal wire, both the camera and the reverse lights stopped working entirely. Reconnecting the original wiring did not restore reverse light function.

Reverse lights completely stopped workingBackup camera not receiving powerReverse lights did not come back even after removing all new splices and reconnecting original wiringAll bulbs confirmed goodReverse lights were working immediately before the wiring work

Root Cause

Cutting and splicing the red/black (reverse light 12V+) wire caused a momentary short that blew the 7.5 amp Gauge fuse in the left kick panel, which controls the reverse light circuit.
