Finally got the wires through but it wasn't fun.  Drilled from the bottom up and thought I was good but I could never get the wire into the engine bay, still a hard stop.  After fish tape from the top down and the bottom up I gave up and used a 2" hole saw into the bottom of the arch.  Turns out I missed the tube by about an inch.  Went back down and drilled another hole from the bottom and perfect this time.  Ran my two sets of wires though and good to go.  Messy job and very sore but well worth it!  These 3300s don't give you much room to work on stuff down there.  Why wouldn't they drill them from the factory???
Oh well, good luck on your projects out there!
