Goose280Z ‘78

Oblithian:   No need to reply to the earlier message, I found a diagram and was able to figure it out.  Really simple.  The fans now come on immediately when I turn on the AC, or once the temp. hits 185 (if I'm not using the AC).   I've attached the diagram if anyone ever needs it.

Hi Oblithian.  I have been enjoying my 78 Z over the past couple of months but the heat here in Arizona  will probably be the death of me (and the Z) if I don’t improve my cooling fans.

I have replaced the OEM clutch fan with a Flex-a-Lite Flex-Wave 16 inch LoBoy puller which produces approx. 3000 cfm. Additionally, I have added 2 12 inch pusher fans on the front to help and to provide more complete flow through the radiator.  I am using a Hayden 3654 (for up to 50 amps) controller with temp control switch, wiring and wattage engorging to run 4 single fans (or 2 dual speed fans) so I have plenty of juice.  The fans I bought will only use approx. 24-24 amps.  There is a wire for connecting to ignition AND a wire to connect for starting the fan when turning on the AC.  The controller is also directly connected to the battery for continual power.

2 Questions:

1) is there a component in the engine well that I can connect the fan controller to which would turn the fans on when I turn on the AC?

2) Are the Z’s able to keep the fans running until the radiator temp hits the lower temp setting, even when the ignition is turned off?  (Would like it to keep cooling during the summer months even after I shut it off)

Any help or advice would be appreciated.
