I know your probably not using the same brand, but I think the principles will be the same. Take a look at the PDFs on Light Tape's website. Perhaps the connectors will be different but the recommendation to run a parallel connection is likely applicable. Your wiring is likely going to get a little tricky so, measure twice cut once. You'll want to seal any cuts in the tape
You probably want to solder and heat shrink any connections. I'd also consider running your wires is lower movement areas. I would use some form of template, so you can measure not only length but also if the tape will bend correctly.
Take a look at this diagram.
