Also - the stock infinity system only has 5 wires going to its harness. Red and yellow are for Ignition and Memory, but what are the other 3? According to my mistubishi adapter harness, the other wires are for Illumination, Dimmer + and the 3rd wire runs to a blank terminal (no connection to anything).
Your post is old, but maybe this info will help someone reading this thread. My 2000 Galant with an Infinity head (MR972458) also has just five wires in the main harness, and the DIN cable to the amp does the rest. According to the shop manual, the wires are:
Pin 4 (Green-White) goes to pin 10 of Junction Block C-74; looks like it is connected to taillight relay, cigarette lighter, license plate light & rheostat.
Pin 9 (Yellow-Black) goes to Joint Connector 2 C-56 & Combination Meter C-30.
Seems to be the Memory that you referred to.Pin 10 (Blue)
Goes to Ignition Switch (ACC) that you referred to.Pin 11 (Red-B(lack?)) goes to Pin 7 of Junction block C-74 through to the Battery.
Pin 12 (Black-Yellow) goes to RHEOSTAT
This is what I can decipher...
