I have been running this on my Z since Friday last week. Thank you, Zeus for starting the project and having Brett finish the final project. My Pictures are on my Instagram page evltwinz. I have a sub harness in-between the factory harness to the r35 coils currently. I had wiring specialties build me a custom sub harness when I was running polar's kit. I just got my new connectors Saturday. I plan on depinning the factory z32 coil connector and installing the factory r35 connector in its place for a more cleaner look.
