You have to have a tune to turn them on. Last time I checked the harness was 80 bucks plush shipping and if you are getting a tune then it shouldnt be too much mroe for the shipping. Go for it. It will be one of my next mods after the nitrous.

I would definately say go for the Nelson harness, I love mine! It looks like a factory installed fan and has been worry free with the harness. They perform better than I thought they would and I never have to worry about messing with them and turning them on because the PCM takes care of it for me.

They should be the same, the only difference would be the appearance (if even that). I would just use whichever set looks the best. You might also want to run a + and - wire to them to see which set runs the best and use that set.
