I bought the cord you linked and selected 4ft. However the 4ft comes before the split. So the split cords are only about 6 inches long. Can you confirm you posted the correct link above? Thank you.
This looks great thanks for sharing. Can you post a picture of how you taped the wires to get to both footwells? The usb splitter you linked seems too short to do the job so I’m curious to see the tape job.
Did you ever figure this out? I’m having the same problem with no power to the pigtail accessories. I checked all 20a fuses under the hood including #84, and they all look fine.
