No
Expert:  James replied 2 years ago.
If both reverse lights aren't working. Make sure both lamps are working and not burnt out. If that is ok they could have been disabled by the body control module. This module often disables the lamps when something aftermarket is done. To eliminate this concern you can wire the reverse lights to the trailer reverse lamp relay and this will prevent the lamps from being disabled again.

The backup lamps are wired to a light blue wire with a white stripe
Expert:  James replied 2 years ago.
The backup lamp is blue with white you are correct. The grey and brown comes off a reverse relay for the trailer adapter.
There is also a grey and brown for the reverse in the trailer adapter. This is for trailer reverse lights
Customer: replied 2 years ago.
So is there 2 grey with brown wires or one
Expert:  James replied 2 years ago.
The brake wire is the same color. So there will be two different wires.
