new head unit matched with old equalizer

Radio Shack sells the din plugs you need to make this up.  You will need one 5 pin male din and three 8 pin female dins.  If you are using 3 amps.  I know that the input plug is an 8 pin plug, the extra pins are to supply constant and switched power to the older Alpine decks. 

Being that I won't be using the old deck anymore, can I just cut the the cable that goes from the deck to the equalizer and put some RCA plugs on it? That is a 5 pin male. I would have to buy the three 8 pin females to go from the front, rear, sub out connectors to the new amp/amps, correct?

I am looking for the same info.  I have an old truck with and alpine 7164 deck and just bought an alpine 3311 eq. I need the pinouts for in and out. rear channels have a 5 pin din out of the deck, front channels go through a line level converter to rca. Amp is 4 channel and has rca inputs. no sub at this point. I have not receive the eq yet so I dont even know if the cables are marked. Thanks in advance.
