Default PCM question

I am working on a project that someone else started and I ended up with it. I have had to do some research on just about every part of the project and I'm at the point now where I want to wire up the electric fans. The PCM that I am using has red and blue connectors. I took a picture of the tag on the PCM I was trying to find the pinouts and the wires to send a ground to the relay for the fans. The person that started this project is no longer available to tell me what he used and how he did it so I'm just searching around in a dark for everything but I could use a pin out for this PCM but I'm not even sure what one it is I know it has the red and blue connectors I know I want to wire up fans to a relay any help would be appreciated I'm going to try and post a picture of the tag

The pinouts you desire are below:

And there will be somebody along shortly to describe a fan relay setup for you. For me on my LS swap, I'm running several Four Seasons part number 35879 fan relay assemblies. No complaints.
