Damn, I love this build!......
Not sure what kind of LED bulbs you are using but many times it's a reverse polarity issue for plug in LED; pull them out and rotate them 180deg and plug them back in and they usually come to life. Ran into this on numerous vehicles to include when I just did the LR3 and I was chasing ground as well. Maybe it helps and I can claim assistance in a mini type way to this epic build.....
