Shot in the dark, SMC wiring, 6 terminals?

[Roc87]

Going to add a little meth to my powerstroke to control EGTs with my larger injectors, I've had this SMC controller lying around that I bought used for years and before I buy parts, want to make sure this thing actually works. My prior SMC box (2001?) had a black&red wire coming directly out of the box and had 4 terminals for wiring. However this box has 6 terminals. Anyone have any ideas which terminal is what? Basically I don't really need anything "fancy" for the truck, just thought having the SMC controller would be easier than a hobbs switch and wiring relays.
