I surplied the picture not knowing what you have. Most '78 cars have the leanburn system thats on the aircleaner.
The one pictured above is the older system. The boxes are black (Mostly a stock color) Orange, a mopar upgrade box often used to replace the crappy leanburn system that often failed.
A MoPar Chrome, a hot rod box
Gold, a Mopar race box.

That box is the controler and is wired up a the diagram shows. Orange box only. Ops, yes, bolted (And grounded) to the fire wall.
If your going this route new, use the Chrome box and other correct parts from MoPar. It works much better than the orange, which has a bad rap latley.
