Scored a set of 06 Tahoe E-fans for it.
Is your alternator & battery gonna be up to the task? I've considered doing this too.How you gonna hook 'em up?
I know my battery can handle it. Not sure yet if the alternator will handle it. Only way to find out is try it out and see.

I have a 130 amp alternator already. I can either get an overdrive pulley to bump the amps at idle, or I can get a 200 amp alternator.
And this is what I will use to wire them up.

I need to talk to Justin and Jenna and see if this will work with my PCM. I may need to tie it in with the AC clutch trigger wire. I am good with wiring, so it shouldn't be a problem.
