I am the confused and I've done this before only with 2 lights not 3. I just wired the outside lights in series without the middle and their not working either. I might just get single drivers from. Going to Walmart rn to get 3pin wagos. This dude on grasscity thru up q diagram.
Like @Rocket Soul said, they need to be connected in parallel with that driver, and your first diagram looks like series. Basically what you want to do is come out the positive of the driver, then split that wire three ways, and connect each of the three to a pos+ terminal on each QB, then do the same thing with the neg- (connect neg to the QB -). Don't connect any boards + to - to eachother.
