Electric Fan Question - Wiring

I am installing dual fans one push one pull.
This is a no brand ebay special to get me by for now. My question is the kit comes with the relay, fans, temp sensor, and a circuit breaker specs below.
My question is I want to eliminate the temp sensor but instead have it kick the fans on as soon as the key is on. I unfortunately have seized plugs on my intake manifold so I just want to go around that.

Wiring
60 Amp Relay
30 Amp Circuit Breaker
30 Amp Inline fuse

The relay has 4 wires
Red with 30 amp inline fuse
Black - Ground
Blue - Fan trigger
White - Temp sensor

Fans - Each
Maximum Fan FAN CFM=2000 CFM
Maximum Fan RPM=2250 RPM
Number of Blades: 10 blades
Thickness=2.5″
12 Volts
6.6 AMP DRAW

So my brain is seeing it connected as battery to 30 amp circuit breaker, Red with inline fuse to circuit breaker
Black to ground source
Blue to fan
White to a ignition switch source? This is what I am looking to figure out if anyone has set up the same please let me know what you used to "trigger" the relay
