Taurus fan wiring

Im looking to get my taurus fan wired up in the next couple of days and have a few questions

#1 any one run the fan in just the LOW setting? Ive read alot of folks running it in just the low setting since high keeps the motor to cool.

#2 I should be ok with running 40 amp realy for the low speed? read alot about a 4 amp realy and 30 amp fuse.

#3 Id really like to wire the ground wire though the relay. So id run a 8 ga power wire from the battery to a 30 amp self resetting breaker then to the low speed lead of the fan. The ground wire would feed trough the realy and be hot when the jeep is started and then the last relay ground activated when a 185 on 165 off switch reaches 185.

For those that know relays heres the terminal numbers
#85 relay ground to temp switch (and dash switch)
#86 relay switch power - from choke relay (relay is activated my the exciter wire from the altenator so it will only come on when the Jeep is running)
#87 to fan ground
#30 to Battery of good ground

Ill use #87A to activate a warning light on the dash to indicate the fan is off.

Any thoughts?
