I had the idea of putting the high voltage cabling inside some clear plastic tubing, but the cables didn't want to go in so I just gave up on that idea. The cables routed below the car doesn't look half to me though.
Plenty of room below the car now. Kind of makes me sad to have all that space that cannot be easily put to use. Oh well. At least I got a lot of crap out that could fail the yearly check.
