Fan relay and sniper install

roger wilco tomorrow. just got home from an epic evening of ping pong. I did have a guy from Derale confusing me earlier and he said the red and yellow go together and the green is attached to the compressor. I have a feeling that the compressor does not need two things triggering it. It is already attached to the hi/lo pressure switch and wonder if I were to use the EFI to trigger it, where would that hi/lo wire go? I appreciate the help I got some instructions in the fan box (black n white) and the color ones in the relay box. Ill get more on that manana.

Thanks fellas!
