Some trucks require a tail light converter. If the truck has an amber tail light, a tail light converter is required. Here is some helpful information specific to Isuzu.
I have an 06 NPR and the shop manual and still missed figuring out why the rear dome lights didn't work. You just saved me so much time trying to understand that rats nest of wires at the back of the frame. You deserve way more credit for this video than the number of views it has. Thank you so much for the effort you took to make this.
I have two rear led integrated lights ( Grote 55162) that I’m using on my travel trailer remodel and it has 4 wires labeled as follows: ground, backup, tail, and ( stop/turn) in same wire but I’m having a hard time figuring out how to keep left and right signals power separated when the stop is shared with same wire? Do I need a converter ?? Thank you for your very helpful video 🙏
