I've done 2 swaps and did both harnesses myself. May have be quicker having Hawks or Pocket do the harness for me, but I'm cheaper than either... 
Oh, and a 3rd is in the works (just not a 3rd gen this time). I'll be doing that harness as well.

Agreed, save yourself a ton of money and gain some invaluable experience.
Take it one step at a time. Label the each connector and work your way from there. Once you understand what goes where and if you need it or not, it becomes a lot easier.
