FiTech EFI system

Played around a little today and finished the install. Got it idling much better but will still have to tinker a little and hope we get some nice warm days to get roads snow/salt free so I can get some street miles on it to let it self learn. Throttle response is killer and from a dead cold (although in my heated shop) it fires right up without touching the throttle.
A couple things I think they should address are; the O2 sensor wiring is way too short to properly run the wires and keep them away from heat (I added about 25" to mine), I would also like to see a longer main power wire and heavier gauge). I had to run a heavier power wire anyway because of my battery in the trunk but still would like to see it come with longer and heavier even if my battery was up front. There was another suggestion but can't think of right now. Overall happy with the quality and ease of installation/wiring.
I will attach a couple pics; now you see it. now you don't :D
How about a ground wire?
