Default manual fan switch?

I want to run a swicth to turn my fans on at the track after a run . Is there a ecm wire to put a swtich inline? Is it a ground or a hot circuit?

I need the fans to come on when the ecm tells it to but I also want it for added safety at the track for cool downs and such . Thanks
