E-fan/ Nelson e-fan harness??
I just installed them yesterday and they both fans were on low, when the ac switched on and a min or two later you can hear them kick on high when compressor kicks on. But my issue is all my lights dim down low for a quick second any time they come on. Turn the ac off its then turn it back on with the regular settings= dim, when switched to high= dim, when the truck gets warm and they turn on= dim of the lights on cluster. Is this a common problem with the e-fans? I also have the 145 amp alt, will be doing the big 3 upgrade soon. I did get the alt to the junction box wire upgraded with 4 guage wire, this is some extra audio cable I had laying around. Thanks for your help, and sorry for the long post.

Yes, it's normal. Think about it - not only is the compressor being kick on, but both of your fans are also receiving full voltage. That's a pretty big amperage kick. Same deal using big amps without a capacitor.
This is why a delay is built in to the factory settings for efans, so that this scenario doesn't happen.
My Camaro's lights would dim when the AIR pump would run - no big deal.
