Here’s a few photos, some taken with the bumper off.
LED light (Labcraft Scenelite) - Positive feed spliced to the reversing lamp positive feed on the inboard side of the nearside tail light / body grommet.
Dedicated grounding point is on the nearside tailgate guide bracket bolt, shown in photo, don’t ground through the common ground wire for the light cluster as the reversing light will flash when the indicators are on!
Garmin BC30 wifi camera unit is spliced in on the inboard side of the nearside tail light / body grommet. Positive to the reversing lamp positive feed and negative to the tail light common ground. Both wires are routed up the nearside D pillar and through the tailgate via the cramped tailgate cable boot.
The reversing light is mounted on a home made bracket under the nearside rear bumper. The bracket is bolted to the thin plastic trim which gives it some shock resilience on rough roads.
