aftrmarket amp into factory deck

Ok. to start off I have a 1998 Saturn SC1 with a factory deck with tape player. I ran all the cables already and my only problem is that I don't know how to connect the High-Low converter into my factory deck. The converter and the remote start is already in the back of the deck and I just have no idea how to connect both into my deck.

what do the connections look like? I may be able to give ya some advice if it's just connection problems; the only thing i've ever done to a saturn deck is remove it from the saturn.
