Manual Fan Override Switch
Hello everyone. I wanted to see if anyone knows how to wire a switch that turns on the fans even when the car is off. Basically I’m looking to do this because my car is a track build and I want to be able to leave the fans on to cool off the engine after sessions. Thanks!

i believe most people connect a switch to some wires
there's been some rumors about wireless switches lately, but i think they're just blowing smoke.

per here, starting at page 338:
http://www.ft86club.com/files/BRZwiringi.pdf both trigger wires(positive and negative) off the relay go into different magic black boxes *my initial impression is that the system is switched negative, with a ign-controlled feed, but the black boxes don't allow me to confirm that easily. if that were true, you would require both a constant power into the relay trigger, as well as adding wire to switch the ground leading away from the relay. so i would suggest running an external relay and switch setup directly off the battery-- my initial impression/assumption of the existing system operation would require 50% of that work anyways.
