Griffen Combo radiator/ fan, relay or factory wiring?

I just bit the bullet and installed a Griffen Combo radiator in my 2000 WJ 4.0. Should I just power the aftermarket fan with the factory fan circuit or install a relay? Thoughts?

screw the factory relay. (leave it hooked up, but don't connect it to any fan) get a new power source, and run a stand alone relay. solder your terminals, and run some large gauge wires (10 gauge strand). get a decent ground as well. stay far, far away from the factory garbage.
