6 bolt coil pack question help
 

i did my swap this past weekend and im trying to wire it up but im not to familliar with it, i have most of it wired but the coil pack plug's are different "the main plug is square and the box a little below the coil pack has a smaller plug than the 2g" can you use a 2g coil pack, and the little box, "sorry i forgot the name of it"
