The sequential lights require the white wire which is the white courtesy lights to have power in order for the sequential function to operate smoothly. See video attached with the door open when the white courtesy lights ( white wire ) have power to them.
When the door is closed and there is no power to the courtesy lights ( white wire ) the sequential lights don’t function properly. See video attached
I don’t want to drive with my white courtesy lights on all the time so I just live with the sequential not working properly
