I change my tail light 2019 dodge charger. It still don’t work

Hi @hmiathoy223

If the front marker lights are working OK but not the rear marker lights (tailights) check if there is 12V on the white/grey wire at the left taillight assembly when the light switch is operated

If there is no voltage there to operate the light then check if there's voltage on pin1 of the distribution connector as shown in the image below. The right side and centre taillights are connected to the white/grey wire at this point.

If there is no voltage there then check if there is voltage on pin 32 of the BCM (body control module - see location in image below)

if there's no voltage at the BCM then there's a problem in the BCM as the front marker lights are working.

If the front lights aren't working then it may be the light switch or light switch wiring between the switch and the BCM.
