classic heartbeat electric fan kit

[76bonanza]

Those that have installed this kit I am doing mine this weekend.
First question is the temp probe for the fan should go thru the rad close to the upper hose right.
Second questions the rubber grommets do they go between the fan and shroud or shroud and radiator.
Last question did you cut off the plugs from the fans or put spade connectors on wires and use plugs?
one more thing it says 20 amp fuses but the fuses in it look like 30 amps?


Thanks
any other tips for this kit would be nice

ps were is a good place to mount a toggle overide switch?
