General LSX Automobile Discussion - HELP!!!! anyone know what this black box is??

i found this tucked away in my engine compartment,it has four ports to plug something in and a wire that runs to ecm.http://s1241.photobucket.com/albums/gg501/fastazzls1/

It looks aftermarket, rpm window switch maybe?

i took it apart and there is no dials or knobs to set any thing,just the four ports on front. could it be for tuning?

Whats it connected to? Could be part of some kind of aftermarket alarm or remote starter system. Any writing on it?

no writing or part # on it, it runs to the ecm. but what would plug in to the ports? i've never saw anything like it so im kinda stumped and would like to know what it is!

Hmmm, yeah I'm stumped

What connector does it run to on the PCM? Red or Blue? What PIN # or what color wire is it attached to? Look up the pin out guide to see what wire this thing is tapped into to see what it might do.
