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?

I think the factory wiring already has a relay.

I’ve had a Griffin Radiator in my Fox body Mustang for 25yrs. I always use distilled water and antifreeze concentrate and there’s no sign of any corrosion etc at all after this long. Good purchase.

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.

One thing I’ve learned about Jeep’s are you can count on the factory wiring / electrical system to fail badly sooner or later. Mechanically they seem quite good but man did they cut corners on electron delivery.
