im installing my elec fan as we speak, i have 2 questions, 1 im hooking it to my ac so it comes on when my acs on, which is the hot wire? the all black one or the black one with yellow stripes. 2.) i need to hook it to a main powersource, so what do i hook it to?

I think most of them are reversable so the wires could go either way.
I know that I'm using a Hayden and they want you to use a 25 amp fuse so hook it up to something major.....

i have a 30 amp fuse, came with my black magic extreme elec fan, but what main power source should i hook it to? i was thinking the headlights but thats not always on, so im going to end up hooking it to the battery, i just need to figure out which wire is the hotwire to the ac.
