Just a quick update, I did get both harnesses and seats installed. Still playing with my wiring, I will post updates as I go. After reading some info I did decide the first easiest place for keyed power is the 12v power port in the console. I have tested running one seat at a time so far with no issues, no wire overheating issues. Because the seat heaters come with a 10a fuse per side, I should be okay. If everything proves out, I will post some more photos with cable routing and some other basic info.
