Multi-Relay Box (Black Box)

[groundpounders]

alright guys i sold this unit to a SHo owner on e-bay i have a few sho's and our club members have a few SHO's along with 2 that we are stripping has we speak. anyway getting back to the subject. i have this black box and would like to know if anybody knows what it year, ATX or MTX will it fit just by the manufacturer numbers on it: F1DF-12B577-AA 333 AND A BIG J i know that these are specific to replace the same units. but the winner would like to know what it will fit. since we have stripped almost 7 SHO's i have no idea what it belongs to. anybody have any ideas?
