Need info on control box

[spyder2k8]

I bought a Gen 3 3SGTE for my MR2 and sitting on top of the ecu was a box with C. S in white letters. It is made by mitsubishi electric corp. It is 4 x 3.5" with three six pin connectors: two female, one male, and one brown loose wire. I looked on the wiring harness at all the connectors but found no matching connectors. The info on the label including: type, no., date and note are unreadable.
