Ok i basicly just want to know if this will work the way i want to wire this please help me out here....

Going to wire my radiator fan to the nitrous/aux input/output

arming input set to always on?

output im going to use pin A20 purge control

now do i need to use a relay to ground, i planned on using a switched 12v power source wired directly to fan and the output wired to the ground side of the fan do i need a relay inbetween ecu and fan for ground?

What exactly do you plan to control with this setup?

The radiator Fan...

Your radiator fan should be controlled by the thermo switch in either the radiator or the thermostat housing.

i know this, but it would be nice if i wired it up so i can adjust when it comes on....catch my drift...im just wanting to know if the ECU is capable of grounding that thing without a relay??

You should always use a relay when trying to activate solenoids and fans or anything that requires any amount of current.

I think the S300 should come with a fan control option.
