Who's got intrepid fans?

[blacknight80]

Anybody install a set of intrepid fans on their car? I'm getting ready to wire mine up through a volvo 2 speed controller relay and was hoping someone had been here before. I am using a thread from syty forum but had a few questions. They controlled the ground with a relay to cut power when the ignition is off. Is it better to control the ground or the hot side?

Thanks
