Hey guys....this actual cooling fan is for the intake ...i'll be mounting this fan in an airduct that'll be able to collect fresh cool air in it's factory location (93 lexus gs300) any suggestions on how i should wire this instead of it's own separate switch?

Not positive what your'e asking here. How about with a simple relay tied to ignition or HU remote for turn on? You could tie it directly to the turn-on lead from the HU if there's enough juice, but I don't know about that.

oh ok...i apologize...i plan on fabricating a cooling fan to lure in cool air into the engine bay using a scoop/airduct....but i want to wire this cooling fan to a place that'll be able to shut off this fan after i've turn the engine off..

Not sure why the air scoop can't do that using air pressure from forward motion, but aside from that, you'll want to use a simple SPDT relay with a trigger tied to the ignition - see the section on relays. Also look into a RAM air intake, I think it'd be better for you.

Just get a cold air induction intake, or make your own using the stiff dryer duct. The only thing a fan is going to do is make noise, and slow down the airflow, unless it is a fan that will move more than 800 CFM. But if you really want a fan, just use a relay and a switch.
