Got my Nelson harness and installed it today on my 03 SS. Worked out nicely, however, I have a little constructive criticism. The wiring could be a hair longer between the PCM mounting point(where the instructions show you to mount it) and the power/ground point this would enable you to route the wiring a little nicer. Also there could be a little less slack between the fan motors. I'm not bitching because the quality of the harness is very high and it looks almost factory. Thanks for a great product Allen.
